摘要：

As a result of experiments and numerical simulation of phase conjugation (PC) in the SBS-mirror with an ordered raster of small lenses, its optimal configuration is determined that has unique properties as compared with the current SBS-mirrors. In current SBS-mirrors in the focused beams the high PC quality takes place at high reflection coefficients only that is often unachievable. The presented SBS-mirror fixedly yields the PC quality that is near to an ideal at any level of SBS saturation, i.e. any reflection coefficient. The simulation results are in good agreement with the experimental data obtained for pulsed Nd laser radiation with using a super-clean SBS-cell and multi-level raster of small Fresnel lenses.
