Demonstration of Optical Phase-conjugation in Methyl Green Dye-doped Thin Film

T. Geethakrishnan and P. K. Palanisamy

Abstract

Optical Phase-Conjugation (OPC) has been observed in Methyl Green (MG) dye sensitized gelatin films in Degenerate Four-Wave Mixing (DFWM) configuration at 633 nm radiation from a He-Ne laser of total power 35 mW. The mechanism of Phase-Conjugate (PC) wave generation associated with this dye-doped system was discussed. The dependence of the PC wave generation on the incident angle between the forward-pump and the probe beams and time of evolution were also studied. A maximum phase-conjugate beam reflectivity of about 0.13% has been observed in this dye-doped gelatin films.
