Laser Diodes 

Thorlabs offers an extensive selection of 

discreet laser diodes in 5.6mm, 9mm and 

VCSEL packages. Ranging in wavelengths 

from 405nm to 1550nm, we have a diode 

to work in nearly any application. Our 

selection of 5.6mm and 9mm diodes 

includes both Fabry-Perot and DFB lasers 

in a variety of standard pin configurations. 

Most of our lasers are fully compatible 

with our entire line of laser diode and TEC 

controllers as well as our selection of Laser 

Diode Mounts (See Pages 459).

Fiber Pigtailed 5.6 & 9mm 

Laser Diodes 

Thorlabs’ full line of fiber pigtailed laser 

diodes (manfactured by either Thorlabs or 

our customers) are assembled at our 

extensive pigtailing facilities in the United 

States. 

A high-quality alignment process ensures 

maximum efficiency at an affordable 

price. 

Our selection includes both single mode 

and multimode pigtails, whose typical 

high-coupling efficiency delivers more 

power from the diode. 

■ 8° Angled-Cleaved Fiber at Laser Diode 

■ Visible to Near IR Models 

■ Single Mode and Multimode Fibers 

■ Angle-Cleaved Fiber to Minimize 

Intensity Noise (Single Mode Only) 

■ Pigtailing of Customer-Supplied 

Diodes Available 

■ DFB Pigtails Include In-Line Isolator 

DFB Laser C-and L-Band 

Butterfly Laser Pigtails 

Thorlabs offers a full range of pigtailed 

lasers with wavelengths centered on the 

ITU grid (100GHz spacing). These lasers 

include polarization maintaining (PM) 

fiber, with an extinction ratio of better than 

20dB and a side mode suppression ratio of 

40dB (typ.). These DFB lasers meet the 

stringent reliability standards for the 

telecom industry. With their built-in 30dB 

optical isolation, thermoelectric cooler 

(TEC) and thermistor, these 20mW lasers 

will provide many hours of reliable 

operation when operated with our laser 

diode current controllers/TEC controllers. 

■ Wavelength: ITU Grid, 100GHz Steps 

■ Single Longitudinal Mode 

■ Accurate Peak Wavelength (±0.5nm) 

■ Built-In Optical Isolator (30dB)

λ = 1512 to 2004nm, P = 0.4 to 0.7mW VERTILAS VCSELs 

Tunable single mode VCSEL (models covering the wavelength range from 1512nm to 2004nm) 

Thorlabs offers a family of VCSEL Laser Diodes that are ideally suited for Tunable Diode Laser Absorbtion 

Spectroscopy (TDLAS) gas detection and monitoring, industrial process control, air quality monitoring, 

and exhaust testing. These unique VCSEL diodes, manufactured by VERTILAS, allow new applications in 

the fields of gas absorption spectroscopy and high speed data communications. The Buried Tunnel Junction 

(BTJ) technology eliminates the overheating problem often attributed to VCSEL diodes. These BTJ 

structures have improved thermal conductivity and reduced device thickness. Consequently, the BTJ 

VCSELs exhibit a reduced temperature dependency on the threshold current. 

The BTJ-VCSELs offer excellent single frequency performance (see Figure 1) at power 

levels around 1mW. Due to their ability to use current for wavelength modulation instead 

of temperature (see Figure 2), these VCSELs allow direct wavelength modulation rates of 

up to 4GHz. This makes the BTJ VCSELs an ideal light source for optical sensing 

applications in the near infrared, especially where fast wavelength modulation is required.

Figure 2: When the wavelength of the BTJ VSCEL is tuned 

over a few nanometers by varying the current, the wavelength 

shift is almost linear (tuning coefficient of a few nanometers 

per mA). The optical power variation ∆P is of the order 

10-30%.

■ Complete with Universal Input 5VDC 

These controllers are designed to supply the low drive current typical of a 

VCSEL. Special attention has been paid to ensuring an extremely clean low 

noise drive current to prevent damage to highly sensitive VCSEL Diodes. 

An integrated current modulation feature allows high-speed sweeping of the wavelength of the VCSEL for spectroscopy 

applications. Alternatively, an analog input enables external modulation of the wavelength. An adjustable upper limit on the 

modulation current protects the laser diode from accidental damage when using either of these features. 

A temperature window indicator LED shows when the diode leaves a desired operation temperature range, thus providing an 

indication that an unwanted wavelength shift may have occurred (VITC002 only). Two other features, an open circuit detector 

and an interlock, both enhance the safe operation of a sensitive VCSEL diode.

Single mode pigtails provide coherent fiber-coupled output from a 

laser diode. Multimode pigtails deliver higher power from the 

diode; however, they do not maintain coherence. Please see the 

beam profile images (below) to choose the correct fiber for a 

specific application. 

Bracket for Fiber Pigtail 

The PTLB1 is designed to mount easily 

and conveniently a LPS or LPM Series 

pigtail to either a breadboard or a TR 

Post. The universal design allows the 

L-bracket to be used with both imperial 

or metric components. The PTLB1 

has a 13/32-40 tap through the 

center of the mounting area, 

allowing the end user to plug the 

pigtail into an SR9 (ESD protection and 

strain relief cable). The PTLB1 makes the 

mounting of pigtails easy for most applications.

IMPORTANT NOTES AND WARRANTY INFORMATION 

ON LASER DIODES/LASER PIGTAILS 

Laser diodes have extremely long lifetimes. However, most 

failures occur from mishandling or operating the lasers beyond 

their maximum ratings. Laser diodes are highly static sensitive. 

Thorlabs cannot guarantee the lasers after their sealed package 

has been opened. We will be happy to extend a full refund or 

credit for any lasers returned in their original sealed package 

within 30 days of purchase.

LDM Series Laser Diode Modules — Blue or Red 

The LDM Series Laser Diode Modules are self-contained laser diode modules, available at 

wavelengths of 405nm and 635nm. These user-friendly devices provide collimated output 

beams and include provisions for attaching our SM1 Series optics packages to allow focusing 

of the collimated beam. 

Containing both a constant current laser diode drive system and a TEC stabilized 

temperature controller, each module offers an extremely stable CW output. The output 

power can be controlled via a user-accessible adjustment pot, a beam shutter, or an enable 

switch. The enable switch is separated from the power switch, allowing the TEC controller 

to maintain temperature while the laser is disabled. 

The LDM Series has all of the required safety features including a keylock power switch, LDM405 

remote interlock connection, beam shutter, and Laser ON indicator. 

Operating from a 9VDC power supply, included with the module, each module can be mounted 

to any optical table using one of our C1502, C1503, KM200V, or VC3 V-groove mounts.

Light Emitting Diode Technologies 

Radiometric vs. Photometric Units 

For many applications, light emitting diodes (LEDs) provide a low cost, reliable alternative to traditional light sources such as the 

incandescent light bulb, halogen bulbs, or arc lamps. Applications involving these former light sources gave rise to photometric measures 

for power, brightness, etc. Since Thorlabs typically provides radiometric specifications for our laser diodes, this overview is to serve as the 

bridge between the two regimes. 

Depending on the LED, the specifications might be given using any of the following radiometric quantities: power (also called radiant 

flux and measured in watts (W)), irradiance (measured in W/m 2 ), radiant intensity (measured in watts per steradian (W/sr)), and radiance 

(measured in W/m 2·sr). The corresponding photometric quantities, which are listed in the table below, are based on the SI unit for 

luminous intensity, the candela (cd). Values reported in candelas are weighted by a spectral luminous efficiency function, which represents 

the human eye’s sensitivity to the light at a given wavelength. Hence, candelas are a photometric unit, thereby giving information about 

the perceived brightness of a source; in contrast, power, irradiance, radiant intensity, and radiance are radiometric units, thus providing 

information about the absolute brightness of a source. 

Based on the candela, three other photometric quantities are also commonly used to specify power measurements for LEDs: luminance 

(measured in cd/m 2 , which is also sometimes referred to as a Nit), luminous flux (whose SI unit is the lumen (lm)), and illuminance 

(whose SI unit is the lux (lx)). Therefore, each radiometric quantity has a photometric counterpart, which is weighted by the spectral 

response of the human eye. 

To convert between radiometric and photometric units, one needs to know the photopic spectral luminous efficiency curve V(), which 

gives the spectral response of the human eye to various wavelengths of light. The original curve, which is shown below, was adopted by the 

Commission on Illumination (CIE) as the standard in 1924 and is still used today even though modifications have been suggested. 

Empirical data shows that the curve 

QUANTITY RADIOMETRIC PHOTOMETRIC has a maximum value of unity at 

Power W Lumen (lm) = cd·sr 555nm, which is the wavelength of 

light at which the human eye is most 

Power Per Unit Area W/m 2 Lux (lx) = cd·sr/m 2 = lm/m 2 

sensitive, and trails off to levels below

where the wavelength is in micrometers. 

According to the definition for a candela, there 

0.4 

are 683 lumens per watt for 555nm light that is 

propagating in a vacuum. Hence, for a 

0.2 

monochromatic light source, it is fairly simple to 

convert from watts to lumens; simply multiply 

0 

the power in watts by the appropriate V() value, 

300 400 500 600 700 800 and use the conversion factor from the definition 


for a candela. 

For example, the photometric power of a 5mW red ( = 650nm) laser pointer, which corresponds to V() = 0.096, is 0.096 x 0.005W x 

683lm/W = 0.33lm, whereas the value for a 5mW green ( = 532nm) laser pointer is 0.828 x 0.005W x 683lm/W = 2.83lm. Thus, 

although both laser pointers have the exact same radiant flux, the green laser pointer will appear approximately 8.5 times brighter than 

the red one assuming both have the same beam diameter. 

Conversion from radiometric to photometric units becomes more complex if the light source is not monochromatic. In this case, the 

mathematical quantity of interest is

V( λ)

where v is the luminous flux in lumens, Km is a scaling factor equal to 683 lumens per watt, E () is the spectral power in watts per 

nanometer, and V() is the photopic spectral luminous efficiency function. Note that the integration is only carried out over the 

wavelengths for which V() is non-zero (i.e. = 380 - 830nm). Since V() is given by a table of empirical values, it is best to do the 

integration numerically.

LED Array Light Source 


LEDs 

The LIU series of LED light sources includes red, blue, green, and white 

LED arrays conveniently mounted in a 1.5" outer diameter housing that can 

be used for a variety of lighting applications. The housing can be readily 

secured in most optical mounts used in camera illumination units. 

Additional mounting options include two threaded holes on the rear of the 

housings, one M4 and one #8-32, as well as grooves running the length of 

the housing that allow the LED unit to be mounted in a 30mm cage system. 

Each LED unit has a 4-pin power receptacle (M8 Straight Socket) on the 

rear of the housing and is shipped without a power cord. The LIU Series of 

LED arrays can be powered by an LIU-PS power supply. The 4-pin power 

receptacle allows for two channel control of the LED light source. When 

operating with 100mA of current, the red, green, and blue LED arrays have 

an output intensity of more than 600µW/cm 2 , and the white LED array has 

an output intensity of more than 1700µW/cm 2 , when measured at a distance 

of 100mm from the LED array along the central axis. 

Features 

■ 20 High Brightness LEDs 

■ Longer Lifetime Than Traditional Light Sources 

■ LED Array Output can be Modulated 

■ Fits Many Commercial Camera Illumination Units 

■ Compatible With the 30mm Cage System 

LIU Light Sources 

Power Cord Not Included 

The AD38 double bored mounting ring holds an LIU series 

LED array in place with a single #8-32 setscrew. The outside of 

the ring is Ø2" so that it can hold any one of many 

optomechanical parts suitable for Ø2" components.

DET Series of High-Speed Photodetectors 

DET10C 

Posts Not Included 

DET10A 

The DET series of photodetectors are compact, versatile, 

high-speed optical detectors. Each model comes complete with 

a fast PIN photodiode and an internal bias battery packaged in a 

rugged aluminum housing. With a wide-bandwidth, DC-coupled 

output, these detectors are ideal for monitoring fast-pulsed lasers as 

well as DC sources. The direct photodiode anode current is 

provided on a side panel BNC. This output is easily converted to a 

positive voltage using a terminating resistor. 

We recommend a 50Ω load resistance for fastest response times 

(see the T4119 shown below).

These photodetectors have a thin profile, enabling use in tight 

spaces. All connections and controls have been moved away from 

the light path. Each DET housing includes a detachable 1" lens 

tube coupler (SM1T1) to aid in the installation of neutral density 

filters, spectral filters, and lenses. The optical head is fully 

compatible with Thorlabs' SM1 Series and SM05 Series assemblies. 

Also available are fiber optic adapters for use with connectorized 

fiber.

APD Series High-Sensitivity Avalanche Photodetectors 


Detectors 

Menlo Systems’ Avalanche Photodetector (APD) series can provide an extremely 

sensitive alternative to traditional PIN photodiodes. The APDs are sensitive and fast 

enough for the characterization of pulsed lasers on the the order of nanoseconds. The 

silicon photodiode of the APD210 provides exceptional performance for low-light 

applications in the 400-1000nm range, while the APD310 covers the InGaAs range of 

850-1650nm. The APD maintains high-gain stability over the operating temperature 

range by utilizing a temperature compensation circuit, which adjusts the ~150VDC bias 

to ensure operation near the breakdown voltage. A 40dB gain amplifier is integrated 

into the package and is AC-coupled to the output BNC. The output is matched to 50Ω 

impedance. The detector has an electronic bandpass of 1MHz to 1GHz and offers a 

user-accessible potentiometer providing a continuous gain adjustment. 

The APD series has SM05 threads for easy integration into Thorlabs’ entire family of 

lens tubes and cage assemblies. The bottom of the detector has a metric (M4) mounting 

hole and an M4 to 8-32 adapter for post mounting. The compact packaging allows the 

APD to be substituted directly into an existing setup while maintaining a small 

footprint on the benchtop.

PDA Series General Specifications 

The PDA series of amplified photodiodes utilizes a thin profile to allow access to light paths 

where there is minimal space. All connections and controls are located perpendicular to the 

light path, making them easy to access. In addition, the PDA series includes a low-noise 

transimpedance or voltage amplifier capable of driving 50Ω loads. Additionally, the 

housing features a removable threaded coupler that is compatible with many of Thorlabs’ 

SM1 and SM05 threaded accessories, allowing convenient mounting of external optics, 

fibers, and apertures. This also provides an easy mounting mechanism to Thorlabs’ cage 

assembly and lens tube accessories. Each housing provides two #8-32 tapped mounting 

holes (M4 for–EC versions) centered on the detector surface. A 120VAC AC/DC power 

supply is included (230VAC for–EC versions). 

Thorlabs' line of Switchable and Fixed Gain Detectors provides gain adjustment over a 

70dB range to take full advantage of the photodiode response range. Gains are adjustable 

from 1.5kV/A to 4.7MV/A in eight 10dB steps. Our selection of wideband detectors 

increase the bandwidth range of DC to -150MHz, while still maintaining low noise. The 

large-area detectors operate with the same switchable gain as described above but use large 

area photodiodes.

PDA10DT 

The PDA10DT uses an extended range InGaAs detector, giving the detector 

a wide wavelength range of 1200nm-2570nm. This detector includes a 

built-in TEC element and thermistor, which stabilizes the temperature at 

10°C. This significantly reduces the detector’s dark current and the noise 

associated with ambient temperature changes. These features allow larger 

gains and lower DC offsets.

PDA8GS 

Features 

■ Wide Wavelength Range of 700-1650nm 

■ Frequency Response of DC to 8GHz 

■ Data Rates up to 10.7Gb/s 

■ Fast 50ps Pulse Response 

Introduction 

The PDA8GS is a versatile, high-speed amplified photodetector designed to 

perform in a wide range of test and measurement applications involving fast 

optical signals. The high bandwidth and high sensitivity make the unit an 

ideal measurement instrument for both pulse response measurements in the 

time domain and frequency response measurements in the frequency domain. 

The frequency response range, DC to 8GHz, supports data rates up to 

10.7Gb/s. The wide bandwidth makes it ideal for evaluating pulsed laser and 

high-frequency modulation applications. Communication applications include 

10Gb Ethernet, OC192, and analog satellite microwave systems. 

The unit incorporates a high-performance InGaAs PIN photodiode coupled 

with a transimpedance amplifier (TIA) that has a gain of 450V/A and a 

maximum input power of 20mW (peak-to-peak) for 60ms or 1.0mW CW. 

The 50W output is DC coupled through a female SMA connector. For 

applications that require AC coupling, an external DC block, mounted in an 

SMA connector, can be ordered with the unit (T8535). The fiber input is an 

FC/PC connector. The PDA8GS uses an internal 62.5µm multimode fiber for 

easy coupling into the receiver. For free-space applications, efficient coupling 

can be obtained by using our fiber coupling and collimation packages attached 

to a kinematic mount or translation stage.

PMM01 


Detectors 

Power Meters 

CCD Cameras 




Spectrometers 

Photomultiplier Tubes (PMTs) are sensitive, high 

gain devices that provide a current output that is 

proportional to the incident light. When light is 

incident on the photocathode of a PMT, electrons 

are ejected from the surface. The electrons then 

cascade down a chain of dynodes, each at a 

successively higher electric potential, until 

reaching the anode. As the electrons cascade, they 

free electrons from each dynode surface, resulting 

in a measurable output current upon reaching 

the anode. 

Thorlabs now offers two photomultiplier 

modules, each with a different PMT. The PMT 

in the PMM01 module has the advantage of a 

smaller dark current and a larger gain; however, 

the PMT in the PMM02 module can be used to 

detect light over a greater spectral range. Both 

modules come with a high-gain, dc coupled, 

transimpedance amplifier. Since these modules are 

compatible with our 30mm cage systems and 

SM1 lens tubes, imaging optics and filters can be 

easily mounted and centered on the photocathode 

of the PMT. Stray and scattered light can be 

prevented from reaching the detector by utilizing 

lens tubes to mount the optical components; this 

is particularly advantageous when working with 

weak or noisy signals.

Introduction 

The PDB100 Balanced Detector Series subtracts two input signals from each other, 

resulting in the cancellation of common mode noise. This allows small changes on 

the signal path to be extracted from the interfering noise floor. Versions offered 

include those with bandwidths of DC to 15MHz, DC to 75MHz, DC to 

100MHz, and DC to 350MHz, along with a switchable version (PDB150) with 

selectable transimpedance gain. Each model is available with either Si (A versions) 

or InGaAs (C versions) photodiodes. To improve the measurement capabilities in 

applications where it is desirable to measure a comparably weak frequency 

modulated signal over a strong CW background signal, 

an AC coupling version of the PDB Series is offered. 

Features 

The PDB100 series of detectors comprise two balanced 

photodetectors and an ultralow noise, high-speed 

transimpedance amplifier. The design allows an 

improved matching of the two balanced photodetectors 

to achieve an excellent common mode rejection, leading 

to better noise reduction. An additional active filter to 

suppress aliasing effects is offered also. 

The detectors have two optical inputs with removable 

and interchangeable connectors – either FC/PC or 

FC/APC. This allows easy adaptation to either fibercoupled 

or free-space applications. However, the FC 

adapter on the PDB130C is not removable.

Balanced Amplified Photodetectors (Page 2 of 2) 

Three electrical SMA connectors provide the balanced 

output signal plus a power monitor for each of the 

two input signals. These two monitors make it 

possible to control the input power levels and can be 

used as an independent power meter for each channel. 

The unit is housed in a shielded and rugged 

aluminum enclosure. The housing has an #8-32 and 

M4 threaded mounting adapter plate that can be 

positioned by the user so that it is located on either 

the bottom or the back of the detector. The latter 

allows the unit to be mounted onto a post by using 

the included screws and allen wrench. A ±12V DC 

power supply is included with each unit.

The IS200 Integrating Sphere is a general purpose sphere for many applications such as laser power, flux, reflectance, and radiance 

measurements. The sphere is manufactured from PTFE-based high-reflective bulk material, making it resistant to heat, humidity, and high 

levels of radiation. The sphere is compatible with Thorlabs’ SM05/SM1 series of lens tubes and the 30mm cage system. 

The port for the direct connection of our SM05PD photodiodes (see page 929) has been specially arranged and limited to a diameter of 

3mm in order to prevent direct irradiation of the detector even for large divergent input beams. The IS200 and the IS236A are available 

as 4-port versions as well.

Ensures Long-Term, Low-Drift Measurements 

Ideal for Lateral Positioning Applications 

One- or Two-Dimensional Sensors 

Available Wavelength Ranges: 

400-1100nm and 900-1700nm 

The PSDM provides a convenient way to obtain useful electrical 

position signals from optical position detectors. The PSDM 

features one or two output signals proportional (see tables below) 

to beam spot position X, or both X and Y, as well as a signal 

proportional to the beam spot power, SUM. In addition, lowlevel 

signals can be sampled for versatile PC signal processing. 

All signals are available through a 16-pin header, whereas the X, 

Y, and SUM signals are also present through BNC connectors. 

Applications 

Applications requiring optical position detectors include noncontact 

distance measurements (triangulation), alignment, beam 

steering/alignment, surface level measurements (AFM), position 

and motion measurements/control, and spectral analysis. These 

detectors are often used in applications to compensate for beam 

angle deflections caused by slowly drifting components in optical 

setups. 

The PSDM provides a convenient solution for useful output 

from a position sensing detector. Eight analog 0-10V outputs are 

provided that determine the precise position of a light spot on 

the detector. Using a suitable A/D converter system, these signals 

can be used to perform a wide variety of measurement and 

analytical chores. Two TTL inputs allow you to switch between a 

multiplication factor of 10 and 100 on two of the output signals.

The PSDM Series is available with one of two types of optical 

position detectors: 

■ A Lateral (or duolateral if two axis responses dessired) Silicon Photodiode 

if Beam Sources with a Spectral Range from Visible to 1100nm 

■ A Quadrant InGaAs Detector with Four Photodiodes and Spectral Sensitivity from 900 to 1700nm 

Lateral Detector 

Quadrant Detector 

Since the position sensing system responds to the 

“center of gravity” of the beam spot, the lateral 

diode position response is highly linear and 

independent of beam diameter as long as it not 

truncated by detector boundaries. A beam spot on 

a lateral photodiode generates a photocurrent, 

which is split into two resistive sheets and fed to 

terminals A and B as shown in the figure below. 

The resistance ratio of the two sheets depends on 

spot position, and hence so does the relationship 

between the two currents. 

With a quadrant detector, the position output 

signals relate to the optical power distribution 

over its four diodes. The position signal gain 

increases as the spot diameter decreases. Quadrant 

detectors are often used to center a beam on a 

particular optic.

Monitor Up to Four Quadrant Detectors as 

a Stand-Alone System or With a Computer 

The PDQ80S1 is a four-channel quadrant detector system with USB 2.0 

interface that is capable of monitoring up to four separate quadrant detectors 

(PDQ80A). Software is provided for displaying the relative beam positions 

on a computer monitor. The PDQ80S1 will also work independent of a 

computer, indicating a centered beam with four LEDs (one per channel). 

This system is ideal for integration into an auto-alignment system. Each 

PDQ80S1 comes with one PDQ80A quadrant detector and a four channel 

detector hub. Additional PDQ80A detectors can be purchased. 

No external power supply is required when connected to a host PC USB 

port (power is drawn from PC USB port). For stand-alone operation, the 

PDQ80S1 may be powered from a USB compatible AC power converter. 

The application software provided with the unit includes a real-time 

graphical user interface with Sensor XY Display (See Figure 1). The scaling 

factors for the GUI provide a maximum resolution of ±1300 units from the 

center of the sensor, with a surface XY beam position detection range of 

±3.9mm from the center for a 3µm display resolution.
