Compact Laser Diode Drivers for Military Rangefinder Applications
Compact and high current laser diode drivers for pumping solid-state lasers have been developed and tested. Designed to operate from a single DL123 battery or equivalent, the OptiSwitch PLDD-150-1-1 delivers 150 A of peak current for 300 μs to a laser diode bar at a 1 Hz repetition rate. Measuring only 2.1 x 0.75 x 0.78 inches and weighing 15.2 g, the unit is suited for man-portable target designation, rangefinding, illumination, and remote sensing applications. This paper will discuss the design philosophy behind this class of drivers which offer peak currents up to 200 A plus lifetime testing of eight drivers all operating at elevated input voltage and temperature at 4.5 Hz for 10M shots without a single failure or degradation in performance. Lastly, temperature testing down to -40°C will be discussed.
The above paper will be presented at the SPIE Defense, Security and Sensing conference in Orlando, Florida next week at the poster sessions. Click on the link below to read the full paper.

OptiSwitch Technology Corporation (OTC) is pleased to announce the availability of a new compact, pulsed laser diode driver capable of independently driving two laser diode bar stacks. The PLDD-120-10-20D is a dual-channel laser diode driver ideal for applications where the user needs to switch between two diode pumped laser sources — for example an integrated laser rangefinder and laser marker/target designator. Switching the output of the PLDD-120-10-20D is achieved by simply toggling a digital signal input. This insures that both channels cannot be fired simultaneously. Each channel of this unit is capable of driving a 10 bar stack to 120 amps with a 300 μs pulse.
