Conjugation heat-transferring in the problem of solid-state laser disk elements thermo-optical condition

摘要

The problem of large-scale solid-state laser disk elements thermo-optical condition is obtained. Conjugation heat-transferring was simulated with help of commercial program CFX. The gas and liquid was obtained as cooler separately. It was shown that thermo-optical properties of liquid strongly influence on laser beam aberration structure in comparison with integral disc aberrations at liquid cooling. Thermo-optical phase heterogeneities of the cooling gas are less than disc aberrations. The most effective method of phase aberration corrections is aperture masking to delete a laser beam part with most strong phase aberrations.
