Objective To design a laser power control system with stable output current and accurate laser radiation time to avoid the fluctuation of laser radiation dose. Methods HSPY-600-01 programmable power was selected as the power supply of laser module, and Modbus was the optimal choice of communication protocol. Based on WinCE 6.0 operating system, this system was able to control accurately the power, operating time, and the turn-on as well as shutoff of the laser module. Meanwhile, the monitoring function was implemented independently, Results This advanced laser power system based on embedded ARM system could minimize effectively the fluctuation of laser dosage by laser source. C.,oneluaion Laser source in medicine must be able to output a stable and accurate laser dosage, and the control system provides steady control and precise monitoring of laser source.
