The PCO-7810 is a compact, economical
OEM laser diode driver module designed toprovide extremely fast, high current pulses todrive laser diodes in range finder, LIDAR,atmosphericcommunications and other applications
requiring high current, nanosecond pulses.
The PCO-7810 features an internal highvoltage DC power supply to support the highcurrent output, and an internal trigger
generator. With the supplied heatsink, thePCO-7810-40-4 can operate at pulse
repetition frequencies up to 200KHz at 40A
output current.

packages), as well as other packages ofsimilar dimensions and lead spacing,
mounted perpendicular to the driver circuitboard. To facilitate different packages andmounting preferences, there are two solder
pads on the end of the board to accept
various laser diode packages mounted on
axis to the driver. Furthermore, the diode canbe connectedremotely from the driver using a
low-impedance stripline interconnection
between the mounting pads and the leads ofthe laser diode.

A current monitor output may be viewed withan oscilloscope, providing a straight-forward
means to observe the diode current waveform
