| 摘 要： | 提出了利用气体的受激拉曼散射(SRS)效应激光雷达光源来探测大气中的CO2气体的新方法,设计出探测大气中CO2气体含量的非线性拉曼增益激光雷达,用Nd:YAG激光器(1064 nm)的三倍频光(354.7 nm)通过分别装有CO2气体和N2气体的拉曼管,分别得到CO2气体和N2气体的受激拉曼散射的一阶斯托克斯线(S1),并用S1线作为雷达的种子发射光源.通过实验得到拉曼管中的气压与S1能量的变化关系,对其优化条件和物理机制进行了分析.该实验方法已经成功测出了大气中CO2气体的回波电压信号.

| Abstract: | It is a new skill to use SRS rays as emitting waves for the lidar monitoring CO_2 gas, and the nonlinear Raman lidar based on the SRS process was devised. The third harmonic Nd:YAG laser wave (354.7 nm) was injected into the Raman cells filled with higher pressure gases, CO_2 and N_2. The first Stokes (S1) line 371.66 nm (CO_2) and 386.7 nm (N_2) were generated by stimulated Raman scattering. The variable S1 energy was measured by changing the gas pressure in the Raman cell and the Nd:YAG laser system output energy. The optimum pressures of the CO_2 and N_2 in the Raman cell were achieved. Moreover, the principles of this physical process were put forward. This skill has been applied to the lidar for monitoring the CO_2 gas. |
