摘　　要：本文从密度矩阵方程出发,分别采用三能级和多组独立三能级迭加的近似方法对光泵NH_3分子亚毫米激光器的输出光强进行了理论研究.同时根据NH_3分子能级结构对TEA-CO_2激光器的10R(6)谱线泵浦NH_3分子亚毫米波频谱特性进行了数值计算,理论计算结果与实验符合较好.In this paper, the gain characteristics of optically pumped NH3 molecular submil-limeter wave(SMMW) laser are studied theoretically by solving the density matrix equation. The approximation of three-level and multi-groups of independent three-level transition system is used. The spectrum characteristics of NH3 molecular SMMW pumped by a TEA-CO2 laser with the 10R (6) line are calculated quantitatively, and the results are in good agreement with those from the experiments.
