Product Overview:

AMI offers you a complete line of laser diode driver systems and modules for military applications including direct illumination and DPSS laser pumping. It has patented techniques that allow products to generate narrow, high-power pulses at high repetition rates and/or CW output in the smallest footprints available.

AMI has developed numerous pulsed laser diode driver designs in a variety of packages for easy integration into customer platforms. All diode driver products provide safety features such as feedback current control, over current/voltage protection, enable/inhibit, and dump circuit functions to prevent damage to laser diodes.

The Model 781 is a compact PCB QCW laser diode diver. It is a single channel, non-isolated compact QCW laser diode driver with high efficiency design will drive diodes up to 2V with 3V input.

The Current amplitude is trimpot adjustable and the output pulse width can be set equal to the input pulse width, fixed at 8ms, and can be truncated by an external detector signal input or by a detector in the laser package, if present (jumper selectable). Threshold adjusts via PCB mount pot (R28) and a test point is provided to set the threshold. Jumper (J8) selects source to truncate pulse: (1) external signal via coax or (2) photodiode inside laser package.
