Taking the SPI optical fiber laser as an example,we introduce the pulse output mode of operation.VC is used to control the STC12C5A60S2 chip to generate PWM wave with adjustable frequency(500Hz-200kHz) and duty cycle to control the fiber laser.At the same time,VC is used to change the laser power through the RS232.The test result shows that this control system can control the laser rapidily and stablily and it meets the needs of industrial production.
