Pulsed Laser Diode Drivers

Pulsed Laser Diode Drivers, Model 779AAMI offers a line of pulsed laser diode drivers for both high current and low current applications.  AMI’s high current high power driver Model 7701A is an OEM design for high power DPSS laser and illumination applications.  AMI’s high speed high peak power Model 766 is ideal for driving 14-pin butterfly packaged laser diode modules for use in pulsed fiber MOPA systems for materials processing, LIDAR systems for remote sensing, laser communication applications and rangefinding.

For laboratory and bench top applications AMI offers the Model 8800D laser diode controller.  This microprocessor controlled rack mount system provides pulsed output currents to drive laser diodes for pumping solid-state lasers. The internal microprocessor provides the flexibility and convenience of software control and the system status is presented on an easy-to-read LCD graphics display. The Model 8800D is an excellent prototyping tool that allows the laser developer operating flexibility to determine the best diode and drive for their end use.  Once the final requirements are defined, AMI can help specify and design an OEM driver tailored to your application that will be cost-competitive, have high reliability and a small footprint

The new 780 Series are efficient pulsed, CW and QCW OEM driver assemblies for operating single high power laser diodes.

The standard products below represent statements of capability.  Most of the drivers AMI sells for OEM production are customized to meet the requirements of the end use.  Please contact AMI today to discuss the specific requirements of your application.
