Description
The PLD-NS-SYNC is a compact short-pulse seed laser diodedriver for powering 10/14-pin butterfly laser diode modules forapplications, which require pulse widths from 1 ns to 100 ns.
The pulse repetition frequency can be varied from 1 kHz to 10 MHz.

The main parameters of PLD-NS-SYNC (outputcurrent, pulse width, repetition frequency,
temperature set, pulse delays in sync mode)
are controlled by computer interface.

The driver is specially designed to minimize jitter between external trigger
signal and optical pulse by enabling external clock synchronization. Thedriver also supports operation in Master/Slave mode and synchronizationof optical pulses between two lasers, one operates as Master andanother one as Slave, with the optical pulse position jitter below 500 ps
and tunable delay between the optical pulses from two lasers.

The PLD-NS-SYNC has an external TTL-compatible
input for repetition rate control from single shot up
to 1 MHz. The driver has an external output forsynchronization with each current pulse. The PLDNS-SYNC has an external input/output of the clock
frequency for synchronous operation of two drivers
with minimal period jitter between optical pulses.

The driver circuitry requires a single 5 VDC power source. Allother needed voltages are generated on 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 current pulse monitor output can be viewed
with an oscilloscope by on-board SMA connector
allowing the user a real time view of the current.
Voltage amplitude 1 V is equal to 2 A current.
Driver has landing pads for soldering a butterfly
laser diode directly into driver board and large heatsink for stable heat dissipation.
