Degenerate four-wave- mixing (DFWM) is an unusual method of holographic grating (HG) recording which enable real-time phase conjugation of light beams. Mainly scalar DFWM has been studied [1]. In this paper, scalar and vectorial DFWM in a-As2S3 chalcogenide and in azobenzene molecular K-RJ-4-3 [N,N-bis(5,5,5-tryphenylpentyl)-4-((4-tritylphenyl)diazenyl)aniline] glassy films are experimentally investigated. Coherent self-enhancement (CSE) of HG in this geometry was studied as well, for the first time to our knowledge.
