PIM-Mini-200 Pulsed Current Source
Precision Pulse Control
The Mini-200 is a compact and lightweight pulsed current source designed to drive laser diodes, bars, arrays, or any low-impedance load. The key specifications are output current from 25 A to 200 A, rise and fall times below 10 µs at 200 A, pulse widths from 25 µs to 250 µs, forward voltage from 0 V to 48 V, and pulse repetition rate from single shot to 200 Hz.
System Operation
The Mini-200 output current may be set with an internal potentiometer or an analog voltage. The pulse width is controlled with the input trigger signal. The system requires two DC voltages for operation, 12 V and compliance voltage equal to 12 V above the laser diode’s forward voltage.
Output Cable
The laser or load is connected to the Mini-200 with 22 AWG twisted pair cable (included) with a length of 15 cm (6 inches) or less.
