Probe types 7<br />
Continuous wave and Superpulsed <strong>probes</strong><br />
Within its product range, Reimers & Janssen offers two types of lasers: CW <strong>probes</strong> and<br />
pulsed <strong>probes</strong>. CW <strong>probes</strong>, also known as continuous wave <strong>probes</strong>, provide a continuous laser<br />
beam, whereas pulsed <strong>probes</strong> emit extremely short light pulse in succession.<br />
With both probe types, the light output can be controlled by frequency modulation. The<br />
Physiolaser automatically determines the attached probe and makes available the appropriate<br />
programme.<br />
You may use therapy programs with pre-programmed frequency modulation or simply programme<br />
the frequencies yourself (individual protocols). For detailed information on this, please<br />
consult the user manual for your Physiolaser.<br />
Please note when using frequencies that the energy output for CW <strong>probes</strong> is always half<br />
that of continuous wave operation – independent of the frequency.<br />
In contrast, with pulsed <strong>probes</strong> – which generally cannot be operated with continuous wave<br />
– the energy is dependent on the selected frequency. The highest energy is emitted at the<br />
maximum frequency. The power output cannot be changed with pulsed <strong>probes</strong>.<br />
If you would like to know the precise relationship between the amount of energy and the<br />
power output with continuous wave and pulsed <strong>probes</strong>, please read the chapter Physical<br />
Principles of <strong>Laser</strong> Therapy on page 29.<br />
