The PLD-NS is a compact short-pulse seed laser diode driver for powering 10/14-pin butterfly laser diode modules for applications, which require pulse widths from 1 ns to 100 ns. The pulse repetition frequency can be varied from 1 kHz to 10 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 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-NS (output current, pulse width, repetition frequency, temperature set) are controlled by computer interface. 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.

The PLD-NS has an external TTL-compatible input for repetition rate control from single shot up to 10 MHz.
The PLD-NS has an external output for synchronization with each current pulse.
Driver has landing pads for solderin a butterfly laser diode directly into driver board and large heat sink for stable heat dissipation.
