AMI’s Model 762 OEM programmable seed laser diode drivers are ideal for driving 14-pin butterfly packaged laser diode modules for use in CW or pulsed fiber MOPA systems.
Applications include materials processing, LIDAR systems for remote sensing, laser communication and rangefinding.
The driver circuitry operates from a single +5V power source. Additional voltages are generated on the board by high efficiency switching power supplies. The laser power input may be operated down to +3V to conserve power at the expense of switching speed. Input laser power may also be increased up to +12V to enhance switching speed for high inductance lasers. For most applications laser power may be tied to the driver +5V supply, or through an external switch as an additional safety interlock.
An on-board field programmable gate array (FPGA) is programmed to handle communications, to modify adjustable features, and to provide external flags and signals to a host system. The FPGA also contains a comprehensive pulse generation system with many programmable features. Adjustments can also be made through analog operation by the use of multi-turn potentiometers and providing an external TTL trigger pulse so a serial interface is not required. The driver supplies a bidirectional proportional-integral-derivative (PID) thermoelectric cooler (TEC) controller with current capability of 3A and voltage capability of 4.2V.
The 762-EXT is offered for those who require agile control of the laser current, want to modulate the current or drive the laser with arbitrary waveforms, pulses with variable rise/fall times or modified pulse flatness. An external control voltage with a calibration of 1A/V is required for this mode of operation and the potentiometer and digital control of the laser current are disabled.
The board is manufactured as a RoHS compliant assembly built to the Directive 2002/95/EC requirements. A heatsink adapter plate to mount to an external heatsink and all required mating cables are supplied with each unit. Contact AMI today to discuss your custom requirements.
