Design of High Power Semiconductor Laser Power Supply Based on ARM

Abstract

In order to improve the intellectuality and human-machine interaction of high power semiconductor laser power supply, STM32F107VCT6 is used as master controller in the constant-current source system of semiconductor laser. By using the 10M/100M Ethernet interface based on STM32F107VCT6, the power supply can achieve network communication. A friendly human-machine interface is designed based on LABVIEW. At the same time, the power supply system provides automatic temperature control and protection for semiconductor laser. The result shows that the power supply can work in continuous wave (CW) and quasi-continuous wave (QCW) modes, whose maximum output current is 70A.
