摘要	Temperature variation will induce the shift of output wavelength of semi-conductor laser to affect control preciseness. To ensure the stable working state of semi-conductor laser, temperature should be controlled precisely. In this study, a genetic algorithm optimized temperature control system was proposed for semiconductor laser. Firstly the structure of the temperature control system was designed, and its effect on temperature and methods and relevant theories of temperature control were simply introduced. Then temperature acquisition, adjustment and control were designed in details. The objective function of PID (proportion, integral and derivative) parameters of the laser temperature control system was established and optimized, and the PID parameters were optimized and adjusted using genetic algorithm. Finally a simulation experiment was carried out to test the performance of the temperature control system. The simulation results demonstrated that the genetic algorithm optimized PID control system could control temperature more stably, which was better than the original one. Hence it is concluded that the genetic algorithm based high-precision temperature control system for semi-conductor laser could effectively control temperature and respond in ultra-short time after environmental changes, suggesting high preciseness, effectiveness and reliability.
