摘要
通过求解半经典的密度矩阵方程 ,计算了在CO2 - 1 0R(6)泵浦下 ,小型光泵NH3亚毫米波激光器中 ,NH3 分子的V2 :aR(0 ,0 )跃迁的频谱特性 .理论计算结果表明 ,当工作气压比某一特定值高或泵功率密度比临界值低时 ,将出现V2 :aR(0 ,0 )跃迁的拉曼频谱尖峰 。
In this paper, the semiclassical density matrix equation was solved to calculate the spectral characteristics of V 2∶aR(0,0) transition in a miniature optically pumped NH 3 submillimeter wave laser (mini-NH 3-OPSMMWL).Which was pumped by CO 2-10R(6) line .The results of theoretical calculation showed that the spikes in Raman spectrum of V 2∶aR(0,0)would appear,when the operating NH 3 gas pressure was higher than a certain critical value or pumping power density was lower than a certain critical value.This was caused by Raman processes interaction of AC Stark splitting.
