【摘要】 本文对CO₂激光束与开式腔远红外激光器的匹配问题进行了分析,给出了远红外工作物质对CO₂激光的吸收率与耦合孔逸出损失之间的定量关系,指出对确定的远红外共振腔有一最佳的匹配发散角。在该角度下,工作物质有最大的激活体积,并可获得较高的远红外激光输出。更多还原

【Abstract】 In this paper the question concerning matching of CO2 laser beam with open resonator of a far infrared laser was analysed, and the quantitive relation between the absorptivity of working material of the far infrared laser and the outgoing loss of coupling hole was given. It was shown that there is an optimal divergent angle for a given resonant cavity of a far infrared laser. At this angle active volume of the working material was maximized, and higher output of the far infrared laser was obtained.更多还原
