Laser Driver Load Assembly

This Laser Driver Load Assembly is designed to emulate laser diodes for evaluating the performance of the laser drivers. These laser drivers can be used to drive one or multiple laser diodes with high efficiency and low noise for DPSSL, EDFA, or fiber laser applications. They accept wide range input voltage and their output voltage can range between 0.V to almost the same as the input voltage. You will be surprised at its small size and yet it produces output high current, high voltage, thus high output power. In addition, these laser drivers have low output noise (except that there is an expected 500kHz 4mVp-p ripple voltage at the output) and wide modulation bandwidth. This laser load assembly can be used with the evaluation board ATLS212EV1.0, used alone, as a dummy laser load, or used to emulate one or multiple laser diodes.
