Temperature plays an important role to the laser, the temperature control system based on TEC is implemented, which uses MAX1978 chip controlled by MCU to heat and cool the laser by adjusting the direction and magnitude of TEC driving current, and designs the optimal control process of PID controller, so that the working environment temperature of the laser can reach the predetermined value quickly and accurately. This system provides a small volume, high precision and convenient operation for the temperature control of laser.
