PHASE CONJUGATION MIRRORS FOR HIGH POWER LASERS

摘要

Experimental researches has been performed of phase conjugation (PC) for the scheme of focusing containing a kino form raster. Conditions have been found under which high-quality PC is obtained. The degree of PC quality (the selector transmission coefficient k_(sel)) has been measured for various schemes with a kinoform raster, and k_(sel) 0.7 has been obtained. The comparison of experimental and calculated data shows their good agreement. The measurements of threshold energies were performed and investigated the kinoform effect on the SBS threshold.
