OptiSwitch Technology Corp. has announced the PLDD-50-SP, a short-pulsed diode driver for rangefinding, remote sensing, and defense and security applications. Measuring 68.6 × 33.0 mm and weighing <14 g, the all-solid-state pulsed current source is designed to drive single- or multichip laser diodes. At 50 A of peak current, it delivers <5-ns pulse widths with pulse repetition frequency variable from single-shot to 15 KHz. Laser diodes can be mounted on the edge of the driver or vertically through mounting holes. The current monitor output provides real-time monitoring of the laser diode current.
