Abstract

A review is presented of researches carried out at Institute of Experimental Physics (Russian Federal Nuclear Center) on creation iodine (wave length 1.315 mcm) and chemical lasers (wave lengths 2.5-4.2 mcm) with SBS - mirrors since 1973. We investigate the operation of the lasers with phase conjugation (PC) for free running mode (pulse duration 1-100 mcs) and Q - switch mode (pulse duration 0.5 -5ns). The competition of the "useful” PC Stokes radiation generation and the "parasitic" generation at the laser transition central frequency at multistage lasers with the high (10^6) gain was studied. We are investigating PC in a wide range of wave lengths. SBS and PC was obtained for wave length up to 4.2 mcm and for radiation with the spectrum width near 700 1/cm. Processes competing with SBS and the methods to suppress them were investigated.
