PLDD-100-20-20D

100 Amp, 20 Bar^†, Dual Channel Pulsed Laser Diode Driver

The PLDD-100-20-20D is a compact, ultra-light weight pulsed current source designed to drive up to two independent laser diode bars, arrays of laser diode bars, or any low impedance load. One channel can operate up to 20 stacked diode bars while the other channel will operate up to a 10 diode bar stack.* The user switches between channels by toggling an input line. This ensures that the loads are not driven at the same time. The unit features a high peak current of 100 amps with a rise-time of <<10 µs (load dependent) and a maximum pulse width of 300 µs. The pulse repetition frequency can be varied from single shot to 20 PPS.

Using the optional Universal Interface Board (UIB-01) the user has easy access to all control pins. Commonly used signals such as the input trigger and the current monitor which allows the user a real time view of the laser diode current are available through BNC connections on the UIB-01 board.

The PLDD-100-20-20D requires a user supplied +11 to +28 volt input supply.
