| 摘 要： | 在CS2介质中观测到由声波引起的布里渊增强非简并四波混频(NFWM)和由分子取向栅产生的瑞利型NFWM.研究发现，分子取向栅与声波之间并不是相互独立的，声波的存在会破坏瑞利型NFWM和布里渊增强NFWM极化之间的相位关系.关键词：四波混频布里渊散射瑞利散射

| Abstract: | We have observed Brillouin-enhanced nondegenerate four-wave mixing (NFWM) induced by an acoustic wave and Rayleigh-type NFWM induced by molecular reorientation in CS2. It was found that the acoustic wave and the molecular reorientation grating are not mutually independent. The existence of the acoustic wave destroys the phase coherence between the polarizations of the Rayleigh-type NFWM and the Brillouin-enhanced NFWM. |
