Powering Lasers
Evaluating Bench Power Supplies
Supplying power to a laser is delicate work because lasers are extremely sensitive and easily damaged. A single pulse of excessive current, lasting only a few microseconds, can overheat and damage the light-emitting facets of a laser diode. While a laser diode driver is the safest and most effective method for powering a laser, in some cases, a bench power supply may be an option. The answer depends on the application and on the performance of the specific bench supply in question. ...
