Various schemes for amplification of Stokes signals are investigated. Some new systems, such as an SBS amplifier in the transient amplification regime and a combined laser amplifier-SBS amplifier, are proposed and realised. Conditions are found under which amplification is accompanied by small distortions of the spatial structure of a signal. A two-pass system for small-signal amplification with phase conjugation is developed by using a PC mirror in the combined amplification system. The gains up to 10{sup 16} were obtained for the phase conjugation quality {approx}80%, the output energy {approx}1 J, and pulse duration {approx}30 ns. (nonlinear optical phenomena)
