Abstract
A system for one-dimensional spatial profiling of a laser beam is suggested, capable of compensating for the spatial laser-beam distortions that arise due to a nonuniform gain distribution over the aperture in the amplifying channel of high-power Nd : glass lasers with wide-aperture stages on disk active elements. The principle of operation, the approach to calculation of the key element parameters, and calculation and experimental results of studying the formation of spatial profiles of the laser beam intensity at the output from the system in question are described. Possible applications of the system both in single-beam and multi-beam optical schemes are considered.
