Development of the nonlinear optical element for light-beam apodization and large-aperture laser amplifier decoupling

摘要

Abstract: Dye cell 'soft' diaphragms for apodization of powerful laser beams are investigated. A cell design with a meniscus lens spacer is proposed to compensate thermal phase distortions in the transmitted laser beam. laser shot-blasted 'soft' aperture technology is discussed. The obtained results have revealed a feasibility to create a wide-aperture nonlinear optical decoupling element - apodizer for application in powerful iodine, neodymium and excimer lasers. !9
