PCO-7810-90-8 Laser Diode Driver Module
Precision Pulse Control
The PCO-7810-90-8 is a compact and economical pulsed OEM laser diode driver module. It is designed to provide extremely fast high-current pulses for driving laser diodes in range finder, LIDAR, atmospheric communications and other applications requiring high-current nanosecond pulses. The PCO-7810-90-8 features an internal high voltage DC power supply to support the high current output, and an internal trigger generator. With the supplied heatsink, the PCO-7810-90-8 can operate at pulse repetition frequencies up to 200 kHz at ≤ 20 A output current (20 kHz at 90 A).
Laser Diode Connection
Mounting pads are provided to mount the laser diode directly to the driver. The four-hole mounting pattern accepts TO-18, TO-5, TO-52, 5.6 mm, and 9 mm packages. To facilitate various packages and mounting preferences, two solder pads at the end of the board accept various laser diode packages mounted on-axis to the driver. Alternately, low-inductance stripline cable can be used for connection to a remotely-located diode.
System Operation
Output current is controlled with the high voltage potentiometer. The frequency is controlled via a potentiometer on the PCO-7810-90-8. A current monitor output is provided to observe the diode current in real time with an oscilloscope.
