长腔HCN激光器工作参数优化

Optimum on working parameters of long cavity HCN laser

对影响长腔HCN激光器功率输出的各种参数进行了调试实验,实验结果表明,激光器的最佳参数为:栅网250目/英寸、工作波导管壁温130oC、混合气体流量21.3sccm、激光工作电流1.3A、工作气体压力147Pa、补充He气流量12sccm。在最佳工作参数条件下,长腔HCN激光器的激光输出为210mW。

The tests and experiments of the various parameters, which affect the output power of the long cavity HCN laser, are performed. It is shown that there exists a group of optimized parameters, under which the output power of the long cavity HCN laser reaches 210mW, these parameters are： grid 250 meshes, waveguide wall temperature 130℃, mixed gas flow 21.3sccm, laser current 1.3A, working gas pressure 147Pa, the added He flow 12sccm.
