摘要

本文介绍了一种高功率、多通道固态激光器装置。介绍了八通道激光模块中自适应系统元件的特性。在激光模块的放大路径的输出波前校正方法，使用泽尔尼克多项式，描述，研究和测试。通过实验，得到了修正由活性元件加热引起的放大路径“热”像差的结果。波前振幅PV = 0.71 μm，其与平面RMS的均方差= 0.11 μm。给出了对该模块剩余信道校正方法的测试结果。

Enhancing Laser Wavefront Parameters in Experiments Using a New-Generation Multichannel Laser Facility

This paper describes a high-power, multichannel solid-state laser setup. The characteristics of adaptive system elements within an eight-channel laser module are presented. A wavefront correction method at the output of the laser module’s amplifying path, using Zernicke polynomials, is described, investigated, and tested. The results of correcting 'thermal' aberrations in the amplification path caused by the heating of active elements were obtained experimentally. The amplitude of the wavefront, PV = 0.71 μm and its mean-square deviation from planar RMS = 0.11 μm. The results of testing the correction method for the remaining channels of the module are presented.
