Abstract
As an important part of the atomic magnetometer, the semiconductor laser's wavelength and power are mainly determined by current and temperature. However, the traditional DC temperature control system would cause magnetic field interference to the atomic magnetometer. Aiming at high-precision current control, temperature control and magnetic field interference, a laser constant current source driving system and Alternating Current(AC) temperature control system were developed. Firstly, a high-precision laser constant current source driving system based on power amplifier was designed. Secondly, the AC temperature modulation demodulation detection and AC heating drive system were designed. Finally, the STM32 controller, high-precision AD acquisition and DA output combined with temperature fuzzy adaptive PID control algorithm were used for high-precision temperature control. The experimental results show that the temperature control accuracy is 0.005℃ at 42℃, and the current stability is 0.5 A at 32 mA, which lays a foundation for laser optical power and wavelength stability.
