【Abstract】 In order to achieve the intelligent control of high power fiber laser, this paper presents the design of fiber laser driver circuit. The system takes STM32F407 ZG as the main control chip. the laser driven current controls by adjusting the frequency and amplitude of the peripheral signal, so as to control the laser output power. It can acquisition and protect temperature and current of the laser pump in real time.The output precision of the current can reach ±0.01 A, which ensures the stability and reliability of the laser.更多还原
