Description
The PLD-PS is a compact short-pulse seed laser diode driver for powering 10/14-pin butterfly laser diode modules for applications, which require pulse widths about 50 ps. The pulse repetition frequency can be varied from 1 kHz to 30 MHz.
The driver circuitry requires a single 5 VDC power source. All other needed voltages are generated on the board by high-frequency switching power supplies. The driver supplies a bidirectorial proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 1,5 A and a voltagee capability of 4 V.
The main parameters (power, repetition frequency, temperature set point) are be controlled by computer interface.
The PLD-PS has external TTL-compatible input for repetition rate control from single shot up to 30 MHz.
The PLD-PS 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 a large heasink for stable heat dissipation.
