Abstract
The possibility of phase conjugation (PhC) of multifrequency radiation of a cw HF chemical laser (HF-CCL) is analyzed. The PhC is based on Bragg scattering from a spatial phase hologram, which is recorded in a resonantly absorbing medium by radiation with a frequency different from any of the conjugated signal frequencies. The mechanism of formation of a spatial phase hologram and the features of optical Bragg scattering on such structures are analyzed. The analysis indicates that the proposed system does not exhibit frequency selectivity and is basically suitable for PhC of radiation with a broad line spectrum. The choice of working components for PhC, Hbr and Xe, is analyzed at length. Numerical calculations are performed, employing a mathematical model present in this paper. The reflectivity is plotted as a function of the component concentration ratio, the intensities of waves determining the volume hologram in PhC-cell, and the angle of the laser beam's convergence. We consider the problem of cooling the medium by mixture circulation.
