We present a study of optical phase conjugation through degenerate four-wave mixing in CuCl, as a function of light frequency, intensity, polarization and sample temperature. The phase-conjugate signal exhibits two maxima at the frequencies of the T 5 exciton (one-photon resonance) and of the biexciton (two-photon resonance). By appropriate combinations of the input beam polarizations, it is possible to single out the various terms contributing to the signal (small-spaced, large-spaced population grating and two-photon coherent excitation). The absolute value of X (3) responsible for the two-photon resonance has been determined ( x (3) (-w,w,w, -w) = 3.10 -7 e.s.u.). It leads to ‘mirror’ efficiencies of the order of 10% for input pump intensities I 0 » 10 5 W cm -2 and sample thickness d» 10 -4 cm. At higher I 0 , a saturation of the reflection takes place. The variation of the conjugate beam with temperature has been studied in the range 15 K < T <70 K. Finally, the phase-conjugate nature of the signal has been verified by inserting an aberrator in the path of the input probe beam, and by checking the reconstruction of the reflected beam.
