| 摘 要： | 脉冲Nd:YAG三倍频激光(355 nm)泵浦CH4的受激拉曼散射第一级斯托克斯光(395.6 nm)用作NO2差分吸收激光雷达的λon.为研究CH4的受激拉曼散射效应和定量解释其物理机理作了数值模拟计算,并作了一系列的实验.通过调节泵浦能量、光束质量和气体压强,得到了各级散射光的能量转化效率与三者间的函数关系,找到了第一级斯托克斯光的优化条件.

| Abstract: | The first Stokes radiation (S1,395.6 nm) of SRS of CH4, pumped by a pulsed Nd:YAG laser at 355nm, is used as λon of NO2-DIAL. A numerical study is done, aiming to explain qualitatively the practically important physical behavior of the configurations. And a series of experiments are reported here on the generation of Stokes orders generated in CH4. By adjusting pumping laser energy, beam quality and the pressure of gas, the relationship between them and the energy conversion efficiency of scattering radiations is obtained. Finally, the appropriate condition to optimize S1 is found. |
