PLDD-X-SP Series

0.05 To 5 Amp Ultra Short Pulse Laser Diode Driver Series

The PLDD-X-SP Series driver is a flexible, compact, all solid-state, pulsed current source designed to drive single or multichip laser diodes. Three models are available with currents ranging from 0.05 to 0.5 amps, 0.2 to 2 amps, and 0.5 to 5 amps. The peak current is adjusted by either an on-board potentiometer or an external DC voltage. The current pulsewidth can be controlled by triggering an on-board pulse generator or by an externally supplied pulse. The pulse repetition rate is controlled by the external trigger.

Solder pads near board edge accept the most common laser diode packages (5.6 mm, 9 mm, TO-18, TO-5, and TO-52). In addition the driver can be configured to interface with the standard 14-pin butterfly package or an optionally installed MMCX connector to allow for rapid disconnect of the load.

The laser diode current can be observed with the current monitor output This high fidelity output ensures accurate determination of the laser diode current.**
