【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.更多还原

【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.更多还原
