PY - 2005 TI - Demonstration of Optical Phase-conjugation in Methyl Green Dye-doped Thin Film JF - American Journal of Applied Sciences VL - 2 IS - 8 DO - 10.3844/ajassp.2005.1228.1231 UR - https://thescipub.com/abstract/ajassp.2005.1228.1231 AB - 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.
