摘要
激光器系统中半导体激光器的功率输出稳定度和工作温度有很大的关系,为了使大功率半导体激光器输出功率稳定,需要对激光器实现高精度、快速温度控制。针对现有的激光系统中激光器温度控制系统存在控制精度不够高、控制速度慢等问题,设计了一种温度稳定系统,采用PT-100热电偶测量激光器温度,并使用最小二乘法对温度数据进行拟合,使得温度测量精度达到0.01℃;使用改进粒子群算法优化(PSO)的PID控制器实现温度控制。仿真实验和实际测试表明,所设计的温度稳定系统能够很好地控制激光器温度,达到目标温度所需的调节时间小于11s,达到稳态后温度波动在±0.02℃内。与传统的温度控制方式相比,所设计的系统能够实现参数自整定并自动调节温度,对大功率激光系统中激光器温度具有良好稳定效果。
The power output stability of semiconductor laser in the laser system is closely related to the working temperature.As the control precision is not high and control speed of temperature control system is slow in the laser system,this paper discusses a new temperature stabilization system.This system gets laser temperature by PT-100 temperature sensor,and uses the least squares fitting to process the temperature data,thus to ensure the temperature measurement accuracy of 0.01 ℃.And the system adjusts the temperature by PID controller whose parameter is optimized by particle swarm optimization algorithm.Simulation experiments and actual test show that of the temperature system can quickly stabilize the temperature of laser,the time of adjustment is less than 11 s.And the fluctuations of temperature is about±0.02 ℃ after the system reaching the steady state.Compared with the traditional temperature control method,the system can achieve self-tuning of parameters and automatically adjust the temperature,the laser temperature in the high-power laser system has a good stability.
