摘　　要：利用Ｆ－Ｐ干涉仪和迈克尔逊干涉仪对光泵ＮＨ＿３分子远红外激光的频谱特性进行了研究，证实在ＣＯ＿２－９Ｒ（１６）泵浦ＮＨ＿３分子时，产生双光子拉曼跃迁辐射；随着ＮＨ＿３工作压强的增加，双光子辐射相互作用增强，频谱展宽．The spectral characteristic of an optically pumped NH_3 molecules FIR laser isstudied by a F-P interferometer and a Michelson Interferometer. We verify that whenNH_3 molecules are pumped by CO_2-9R(16)line,a radiation by Raman transitions of twophotons is produced.Wheh the pressure of NH_3 gas increasing,the interaction of theRaman transitions increase,then the radiation is enhanced and the radiation spectrum isbroadened.
