drivers are found in particle counters, manufacturing vision systems,
photovoltaic quantum efficiency testers, wavefront scanners, fibre
aligners and laser diode LIV testers.
PLD laser diode drivers allow the
laser to be driven from a separate power supply up to 30 V in order to
accommodate high compliance lasers, or multiple stacked lasers.
Built-in safety features of the PLD include: latching current limit,
slow start circuit, and a mechanical shorting relay protect the laser
and ensure long-term system reliability and remote enable can be tied to
a safety interlock and a temperature controller, such as Wavelength's
