Abstract:
In the applications of the semiconductor laser , the driving circuit directly affects the stability of the laser . A design solution with high efficiency , stability , wide range of power was put forward . In order to realize the stable closedloop control ,Sampling resistor and constant current circuit will be made use of , Then it gets a constant driving current . Using the themistor temperature properties and the control circuit of temperature with MCU control system , It obtains the temperature control of closedloop, which meets requirenment of stable temperature control.With the constant temperature , constant current and MCU system,a design solution of closedloop control will be realized. Experimental results show that the power measured by power meter has a good linear relationship with driving current and the range of power is wide. The circuit has a reliable long working time ; The laser has reliable monochromaticity ;System is reliable.
Key words: laser;constant current;constant temperature;driving circuit
