y Gang Liu, Nan Shi, and Hongtao Zhou, Analog Technologies, Inc. Chopping a laser beam is often a necessary practice. For a diode laser, it is much simpler and less costly to chop the beam electrically, rather than mechanically.(more)

Thermoelectric cooler (TEC) controllers are becoming more prevalent in thermal management designs because they can drive a thermoelectric cooler to stabilize the temperature of laser diodes or passive components used in communications equipment.(more)

ATLS8A216 is a laser driver module with high voltage and constant current, which is used for driving one or multiple laser diodes. This laser driver module has several valuable, important, and great features that difficult to achieve at just one module. For example, high efficiency ≥90%, wide input and output voltage range, high output current 8A, low output noise, wide modulation bandwidth DC ∼20kHz, and compact size 27.4×21×5.7 (mm).(more)

Why laser diode needs to be driven by a constant current laser driver?(more)

Diode lasers are valuable but vulnerable devices, and when you need to test a new laser driver, it’s better to use a dummy laser. ATI has developed such a dummy laser, i.e. a load assembly for testing laser driver, ALLD10A14V. This load assembly allows a current of up to 10A and the reserve voltage on each diode can be 150V. Moreover, it can bear a current of 100A for a short time, while regular laser diodes only allow a current 1.5 to 2 times higher than the rated value. Therefore, we can see that this load assembly would be stronger and more durable than regular laser diodes.(more)

When it comes to the question, good diode laser driver, of course, different people have different definitions for it as customers have various applications for the laser drives, for example, they may need constant current laser drivers, high power laser drivers, or high speed laser driver, and etc. The product I am going to introduce now is one constant current laser driver, whose part No. is CWD-01-V2-D.
