摘要
利用汞原子6~1S_0—7~1S_0双光子共振四波和频产生了125nm的相干辐射.对双光子共振增强效应、双光子共振克尔(Kerr)效应进行了研究.讨论了平面波和聚焦情况下最佳相位匹配的条件.实验中还观测到了四波参量振荡和四波差频的信号输出.
Coherent radiation near 125 nm is generated by 61S0-71S0 two-photon resonant four-wave sum mixing (ω4 = 2ω1+ω3) in Hg vapor. The two-photon resonant enhancement and two-photon resonant Kerr effect have been investigated. The optimum phase-matching conditions of plane wave and focusing beam have been analysed. The signals of four-wave parametric oscillation and four-wave difference frequency mixing have also been observed.
