Seed Laser Diode Drivers

Seed Laser Diode Driver

AMI offers a line of diode drivers designed for driving seed laser diodes for fiber laser applications. Our drivers can power most type 1 butterfly packages.  A variety of pulse width, power and control options are available.

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 763 OEM seed laser diode driver is implemented as a transconductance amplifier (analog voltage in, scaled current out). The driver circuitry operates from a single 5 V power source. All other needed voltages are generated on the board by high efficiency switching power supplies.

The Model 766 offers user-adjustable pulse width capability as low as 150ps up to 1 ns at output currents up to 1.1 A. The driver circuitry operates from a single 5 V power source. All other needed voltages are generated on the board by high efficiency switching power supplies.

All three drivers listed above supply a bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 3 A and voltage capability of 4.2 V.

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.
