Paper Abstract

The application of the solid state lasers has been greatly expanded in many domains. The laser system is required to be highly integrated. In this paper, an integrated design scheme of laser diode pumped solid state laser is proposed. The size of the device is reduced by integrating the laser power source with LD pump module. The MCU and low-temperature drift drive circuit is utilized as the hard core. The simplified effective pre-stage DC-DC power source and a quasiresonant full-bridge temperature control circuit are designed. The deep negative feedback for the discharge control loop is concluded in the design. The TEC is used and the control accuracy is ±0.5℃ by the using of predictive PID. The ripple and rise time of the current waveform is tested and the stability of the power supply operated at 20Hz is verified by the load test. The experiment results reveal that this system has good load capacity and stability. Compared with the previous power supply system, this system is small and compact. The power supply efficiency is improved by more than 10% and the size of device is greatly reduced.
