摘要
在求解NH_3分子三能级系统密度矩阵的基础上,用迭代法计算了长为10cm—1.5cm的5支超小型光泵远红外激光器(OPFIRL)的输出激光能量密度和频谱特性.实验研制的5支超小型OPFIRL成功地产生了远红外激光.研究表明:纵向腔效应和横向反馈效应对超小型OPFIRL激光输出有积极作用,对最佳工作气体压强和频谱特性有重要影响.
Based on the density matrix equations of three-level NH, molecular system, power density of FIR laser from mini-OPFIRL was calculated numerically by iteration method. Five OPFIRLs with sample tube 10cm, 5cm, 4.3cm, 3cm and 1.5cm in length respectively lase sucessfully.Longitudinal cavity effect and transverse feedback effect are proved to be active in mini-OPFIRL, and have important effects on the optimum operating gas pressure and spectral characteristic of mini-OPFIRL.
