Paper Abstract

Degenerate-four-wave mixing (DFWM) is an important technique for the generation of phase-conjugate wave, to which much attention has been paid. In this paper. a tunalile CW CO2 1.aser is used as the pump sourse and gaseous SF6 as the nonlinear medium, the dependence of reflectivity of phase-conjugate wave generated by DFWM on the pump intensity, the pressure in SF6, the angle between the pump and probe beams as welt as the potarization of the optical fields etc, is investigated experimentatty and exptained theoretically. Peak reftectivity of 2.1x101 is abtained at P=4 Torr in the gaseous SF6. In the Doppler-free phase-conjugate spectrum of SF6 five absorption dips are observed and the spectral resolving power is measured to be about 3 MHz.
