Reflectivity and quality of phase conjugation of CO/sub 2/ laser radiation by four-wave mixing in a medium with thermal nonlinearity were investigated experimentally. High reflectivity produced by four-wave mixing in CCl/sub 4/ was demonstrated both for pulsed radiation (180 percent) and for CW radiation (20 percent). A self-pumped phase-conjugate mirror based on four-wave mixing with feedback was realized. Energy, spatial, spectral, temporal, and polarization characteristics of radiation generated by four-wave mixing with feedback in CCl/sub 4/ were investigated. The minimum threshold energy of the input signal amounted to about 8 mJ; the maximum energy reflectivity was about 5. The spatial structure of radiation generated in the scheme of four-wave mixing with feedback was investigated theoretically and the conditions for phase conjugation, both for regular and for speckled signal beams were determined.
