摘要
建立缓冲气体对光泵亚毫米波激光作用的理论模型,通过量子力学理论推导了缓冲气体退激活几率,从而使缓冲气体的作用能够定量进行计算.实验上对CO29(R30)泵浦NH3分子67.2um谱线作了测量,实验结果与理论计算吻合得较好.这一工作对寻找光泵小型腔式亚毫米波气体激光器的高效缓冲气体有指导意义.
The model of buffer gas effect on optically pumped submillimeter wave laser was established. And the deactivation rate of buffer gas was deduced by quantum theory, so that the buffer gas effect could be calculated quantificationally. The CO2-9(R30) laser pumping NH3 67.2um line was calculated theoretically and measured experimentally. The experiment results agree with the theoretical calculation. This work would be in favor of finding high-efficient buffer gas of optically pumped submillimeter wave laser.
