Optimization of laser amplifiers with spatial filtering. IV. Deformation of pulses in laser amplifiers

V. V. Lyubimov, L. V. Nosova


Abstract: Gain diagrams are used to study pulse deformation which must be allowed for in the case of series connection of amplifying stages. The concept of an effective pulse duration is introduced. This concept is used to estimate the maximum breakup integral and to determine the optimal parameters of series-connected amplifying stages in the case when the breakup integral is constant for each stage.
