【摘要】 利用光栅选频TEA-CO₂激光器作为泵源,泵浦小孔耦合输入输出的长2m、直径34mm的稳定腔远红外激光器,以CH₂Br₂、CH₂I₂、CH₃F和D₂O气体作为工作物质,得到了波长从66μm至496μAm范围内的40条远红外激光谱线,其中CH₂Br₂和CH₂I₂远红外激光工作物质以及13条远红外激光谱线未见有过报道。我们对这些谱线的波长进行了测量,并讨论了其中部分谱线相对应的跃迁。更多还原

【Abstract】 40 FIR laser lines, including 13 newly-observed ones, with wavelengths ranged from 66μm to 496μm are observed in CH₂Br₂, CH₂I₂, CH₃F and D₂O, which are pumped by a grating-tuned TEA CO₂ laser with length of 2m and active volume of 1500×38×38 mm³. The FIR laser tube with a hole-coupling stable cavity is 2m in length. Its inner diameter is 34 mm, Two new FIR media, CH₂Br-2 and CH₂I₂, are reported. The wavelengths of all the newly-observed lines are measured.更多还原
