Analog Modules, Inc. (Longwood, FL) recently released its short pulse seed laser diode driver, Model 766. The Model 766 offers user-adjustable pulse width capability as low as 150ps up to 1ns for driving 14-pin butterfly packaged laser diode modules at output currents up to 1.1A. Applications include seeding fiber lasers for materials processing, time-resolved spectroscopy, LIDAR and others. The driver circuitry operates from a single 5V power source. All other needed voltages are generated on the board by high efficiency switching power supplies. The driver supplies a bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current capability of 3A and voltage capability of 4.2V.
