Analog Modules has released its Short Pulse Seed Laser Diode Driver, Model 766. The product offers user-adjustable pulse width capability as low as 150ps and as high as 1ns, for driving 14-pin butterfly packaged laser diode modules at output currents up to 1.1A.
Applications include seeding fibre 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 by high efficiency switching power supplies. The driver supplies a bidirectional proportional-integral-derivative (PID) thermoelectric cooler controller (TEC) with current a capability of 3A and a voltage capability of 4.2V.
