Phase Conjugation Using Four-Wave Mixing in Fast Green FCF Dye-Doped Gelatin Film

الملخص EN

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 50 mW.

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.
