摘　　要：利用强激光场驱动下的原子二能级模型 ,探讨了高次谐波与高阶拉曼谱的相干相消现象。结果发现适当选取激光场的强度使高阶拉曼线处于谐波位置时 ,由于相干效应 ,高阶拉曼谱得到抑制而高次谐波谱则得到加强。Interference phenomena between high harmonics and hyper Raman lines in strongly driven two level atomic system has been investigated. It is shown that the hyper Raman lines disappear, the background noises are restrained and the high harmonics are enhanced due to the interference effect.

关 键 词：光学相干 高次谐波 高阶拉曼谱 二能级原子系统
