| Abstract: | The change of current and temperature has great impacts on the performance of low power semiconductor laser diode. Here a laser stability control method is given. Through the design of the constant current circuit to stabilize the working current and double temperature control circuit to stabilize the working temperature, a stab.e current and temperature cricumstance is created for the semiconductor laser diode. The results show that semiconductor diode laser works steady. The working current changes within the range of/IA and the working temperature changes in 10 2 ~C r~nge. And thus the design requirements is met. |
