Description
The PLD-NS-GSS is a compact short-pulse seed laser diode driver for powering 10/14-pin butterfly laser diode modules for applications, which require nanosecond pulse with long rise time. The pulse repetition frequency can be varied from 1Hz to 1MHz.
The driver circuitry requires a single 5VDC power source. All other needed voltages are generated on the board by high-frequency switching power supplies. The driver supplies a bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 1.5A and a voltage capability of 4V.
The main parameters of PLD-NS-GSS (pulse current, bias current, pulse width, repetition frequency, temperature set) are controlled by computer interface.
The PLD-NS-GSS is specifically designed to suppress gain switching by controlling the bias current.
The PLD-NS-GSS has an external TTL-compatible input for repetition rate control from single shot up to 1 MHz.
The PLD-NS-GSS has an external output for synchronization with each current pulse. Driver has landing pads for soldering a butterfly laser diode directly into driver board and large heat sink for stable heat dissipation.
