摘要
讨论了在铯（Ｃｓ）原子蒸气中的光学三阶谐波的产生。理论分析表明，铯的非线性极化率系数Ｘ￣（３）（３ω）在λ＝１．０７９０μｍ处存在双光子共振增强效应，给出了为达到位相匹配所需的温度。实验获得了１．０７９０μｍ光波作用于Ｃｓ所产生的三阶谐波谱线（３５９．７ｕｍ）的照片。
Optical third-harmonic generation in Cesium medal vapor is discussed in this paper.The theoretical analysis shows that there is a two-photon resonance enhancement effect for nonlinear susceptibility X￣(3)(3ω)of Cesium at wavelength 1.0790 μm.The temperature which is necessary to achieve phase matching is given. It's the first time that the third-harmonic spectral line(359.7 um) of the fundamental wave 1.0790μm in Cesium vapor is photographed experimentally.
