Phase conjugation using four-wave mixing in fast green FCF dye-doped gelatin film

Abstract

We present optical phase conjugation based on the degenerate four-wave mixing (DFWM) arrangement in gelatin films doped with acid blue 3 dye (FAST GREEN FCF) using He-Ne laser of total power 50mW. Various parameters which influence the phase-conjugate (PC) signal during the DFWM process were studied (angle of between the forward pump and the probe beam, transition of gelatin film, reflectivity as a function of forward and backward beam). A maximum phase-conjugate beam reflectivity of about 0.02 has been observed in these dye-doped gelatin films. PACS: 42.65.-k, 42.65.Hw. Copyright © 2009 M. H. Majles Ara et al.
