Description
The PLD-PS-SYNC 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 is specially designed to minimize jitter between external trigger signal and optical pulse by enabling external clock synchronization. The driver also supports operation in Master/Slave mode and synchronization of optical pulses between two lasers, one operates as Master and another one as Slave, with the optical pulse position jitter below 500 ps and tunable delay between the optical pulses from two lasers.
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 bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 1.5 A and a voltage capability of 4 V.
The main parameters of PLD-PS-SYNC (power, repetition frequency, temperature set point, pulse delays in sync mode) are controlled by computer interface.
The PLD-PS-SYNC has an external TTL-compatible input for repetition rate control from single shot up to 30 MH. The driver has an external output for synchronization with each current pulse. The PLD-PS-SYNC has an external input/output of the clock frequency for synchronous operation of two drivers with minimal period jitter between optical pulses.
Driver has landing pads for soldering a butterfly laser diode directly into driver board and large heat sink for stable heat dissipation.
