水冷和半导体制冷片联合控温的固体激光器实验装置

摘要

光泵浦的固体激光器的工作介质在工作时温度很高，会产生热透镜效应。这种热透镜效应会导致光-光转换效率下降。为了使激光器的工作介质在工作时保持恒温，研制了一种水冷和半导体制冷片联用控温的装置，根据实验数据可知，本装置达到了良好的效果。%The optically pumped solid state laser media produce a lot of heat when it’ s working, and creates thermal lens effect. The thermal lens effect leads to reduce the optical to optical conversion efficiency. In order to make the working solid state laser media constant temperature at work, this paper developed a temperature control system of water and semiconductor refrigerating sheet, and the experimental data shows that the device achieves good results.
