Abstract

At present, the division of labor in the manufacture of lasers is becoming more and more refined, and some manufacturers specialize in the production of laser power supplies. In the field of laser power supply can be further divided into laser power supply and laser power supply control system, especially laser power supply control system often need to be personalized according to individual needs of manufacturers. However, the control interfaces of these laser power supplies are generally similar, and laser control systems can be developed according to these interface definitions. For these similar control interfaces, this paper designs a laser power control system based on STM32.The system carries STemWin to realize the human-computer interaction function, while the system uses RTOS to realize the integration of each software module. Based on the PWM signal generated by STM32, continuous analog control signal output with PWM amplified signal is realized through the driver board. The final result is an adjustable operating voltage of 0-1000V and an output frequency of 1-20Hz. And it is applied to the laser power supply, the working condition in the actual working environment is good, for the follow-up further optimization also laid a foundation.
