Design optimization of the characters measurement system of 4×2×3 multi-slab-amplifier

The soft aperture slots and multi spatial filters had been used to transmit the same phase of laser beams, the characters measurement system of 4×2×3 multi slab amplifier design has been optimized by a program of Fresnel, where the sizes of pinholes of spatial filters which influence laser propagation have been analized here, the design optimization result also discussed, and the methods and results obtained in this paper are applicable to the design of high power solid laser amplifier system.
