<strong>IPG</strong>’s EAR-LP-SF Series is a line of universal<br />
broadband, high power, lin<strong>ear</strong>ly polarized,<br />
single-mode <strong>fiber</strong> <strong>amplifiers</strong> covering the<br />
spectral range from 1540-1600 nm. The <strong>series</strong><br />
includes 1-30 W versions. These user friendly<br />
and highly efficient 19” rack mounted devices<br />
are designed for maintenance-free<br />
applications over a temperature range of 0°C<br />
to 50°C. The EAR-LP-SF Series is optimized<br />
for lin<strong>ear</strong>ly polarized (LP), single frequency<br />
(SF) input signals and can be used for a<br />
variety of applications including coherent<br />
beam combining, detection systems,<br />
free-space communications and other<br />
laboratory and in-field applications. <strong>IPG</strong>’s<br />
EAR-LP-SF Series <strong>amplifiers</strong> do not need<br />
water-cooling or replacement parts. and<br />
require only 110/220V AC power source to<br />
provide amplification for your low power<br />
signal.<br />
The standard EAR-LP-SF Series amplifier<br />
provides amplification of lin<strong>ear</strong>ly polarized<br />
signals in the 1540-1600 nm region. Typical<br />
bandwidth of the amplifier is 10-20 nm<br />
(depending on output power) which allows<br />
tunability of the input signal for exact<br />
wavelength matching. Amplifier input and<br />
output are provided by a 1-2 meter optical<br />
<strong>fiber</strong> cable with connectors at the input and a<br />
beam collimator (standard beam diameter is 1<br />
mm) at the output. The standard amplifier has<br />
a 25-30 dB input optical isolation and 100,000 hrs at 25°C.
