Product Overview:

AMI’s Laser Diode Drivers incorporate over thirty years of industry experience in providing end users with active current control and protection for their laser diode.  AMI offers a wide variety of drivers for the expanding number of diode pumped and direct output laser diode applications.

The Model 774A is a highly efficient and robust pulsed laser diode driver which is offered for military applications. It is designed to supply pulsed high current for laser diode stack loads. These drivers are low voltage DC input power converter/laser diode drivers designed to supply pulsed high current for stacks loads in applications such as missile, ground vehicle, ship, and airborne applications.

The Model 774A offers a very stable performance over a long lifetime. It exemplifies this technique and delivers up to 200 amps at 44 volts (8kW peak).  It includes a power converter stage to charge up the storage capacitor from a variety of inputs and a very high quality sealed storage capacitor.

The pulsed output current is 200A with ≤ 45μs risetime into diode stacks of 24V to 40V at an average power to the load of 27W at 20Hz. The driver weighs 7.0 oz. in a compact package.

This unit does not require a heatsink and offers open circuit, short circuit, and thermal overload protection.

Please contact AMI to discuss your OEM requirements. Other input voltage and output current/voltage ranges available.
