Abstract: The geometric-optics approximation is used in an analysis of the energy relationships governing counterpropagating spherical beams under steady-state stimulated Brillouin scattering (STBS) conditions. An experimental investigation is reported of an oscillator–amplifier phase-conjugating mirror relying on STBS in nonlinear media of CCl₄ and GLS22P glass. These results are used in derivation of relationships describing the energetics of the operation of such mirrors in a wide range of pump energy densities (up to 12 J/cm²). It is shown experimentally that the efficiency of a phase-conjugating mirror made of GLS22P glass can be increased by shifting the frequency of an acoustic resonance in an STBS amplifier.
