Abstract

An adaptive system for the compensation of static and thermally induced wavefront aberrations of the amplification path of the 'Luch' laser facility is described. This system provided the reduction of the amplitude A of wavefront aberrations of high-power radiation and the standard deviation σ by a factor of ∼3: from A = 9.6 μm, σ = 2.4 μm to A = 3.2 μm, σ = 0.6 μm, which decreased the radiation divergence by half.
