Design of High-Power Diode Laser Power Source by Single Chip

The digital Semiconductor Laser’s Driving Source is designed in this paper, in order to gain a constant current source, which the maximize output electric current is 40A; voltage is from 2V to 10V. Based on the requirement of very task, the part of driving and the part of constant temperature control, which is auxiliary designed, are made of the controller of semiconductor laser diode. As the result, the whole of designs ensure the diode laser to work stably.
