AMI’s Model 762 OEM programmable seed laser diode drivers (pump laser diode drivers) are ideal for driving 14-pin butterfly packaged laser diode modules for use in CW or pulsed fiber MOPA systems for materials processing, LIDAR systems for remote sensing, laser communication applications and rangefinding.

The Model 772A is a highly efficient, low voltage DC input power converter/laser diode driver designed to supply pulsed high current for laser diode-stack loads.

AMI offers a line of diode drivers for both high current and low current applications. AMI's Model 7701A is an OEM high current driver designed for high power DPSS laser and illumination applications. The compact OEM package provides currents up to 300A pulsed or 50A CW via a floating output. The Model 7701A employs a DB-25 connector for external control and a heat sink and fan are provided.

The 779A Series provides currents up to 120A pulsed or 30A CW. The Model 779A allows for trimpot or external adjustment of current amplitude, pulsewidth, and pulse repetition rate and trimpot adjustment of over-current limit. AMI's Model 5705 can be used as an external power supply for either driver.

The new 780 Series are efficient CW and QCW OEM driver assemblies for operating single high power laser diodes. Consult factory for militarized and RoHS version.

Laser Diode Controllers

The Model 8800D laser diode controller provides pulsed output currents to drive laser diodes for pumping solid-state lasers. An 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 8800D can be configured with one or two power modules for up to 2.8kW of output power. Protection features of the 8800D include an adjustable precision current limit which protects the laser diode from exceeding its maximum rating.

For strictly CW applications, the Model 880D CW diode controller offers higher average powers at a reduced price. The Model 880D includes an active power factor corrected front end and can be configured with two or three internal power modules to provide up to 6kW for CW diode loads. Control of the Model 880D can be achieved from the front panel or remotely via an RS-232 interface. An external gate input allows for quasi-CW operation of the Model 880D.
