PCO-7114-50-4 Laser Diode Driver Module
Precision Pulse Control
The PCO-7114-50-4 is a compact and economical pulsedcurrent OEM laser diode driver module that outputs up to 50 A at a fixed pulse width of ≤4 ns. It is designed to provide extremely fast high-current pulses for driving laser diodes in range finder, LIDAR (Light Imaging, Detection and Ranging), ADAS (Advanced Driver Assistance Systems), atmospheric communications and other applications requiring high-current nanosecond pulses.
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 strip line cable can be used for connection to a remotely located diode.
System Operation
Output current is controlled with the voltage at the high- voltage input. The output frequency is the same as the pulses fed to the trigger input.
A current monitor output is provided to observe the laser diode current in real time with an oscilloscope.
