Abstract

A simple quality model of stimulated Brillouin scattering of focused beams is suggested which allows us to quite accurately describe the shape of a Stocks pulse. For a case of totally overlapping pulses we have theoretically and experimentally investigated peculiarities of laser pulse deformations under amplification in two-pass and four-pass amplifiers with a phase-conjugate mirror when pump and spontaneous emission are neglected. Approximate formulas for determination of output pulse duration and duration of the pulse leading front are obtained. Parameters permitting to more effectively control the output pulse shape are found. We also suggest some ways to change the duration of a laser pulse without any significant change in its energy.
