Abstract:
The process of gravitational convection which arises as a result of the heating of a gas by an optical beam as it propagates in a horizontally positioned cell with the square cross section is considered. A program which can be used to calculate the structure of the planar convective flow and the temperature distribution over the cross section of the cell has been developed. The operational efficiency of a modal and segmented mirror for correction of the phase distortions appearing during the propagation of the optical radiation in the radiation-induced thermal inhomogeneities is investigated.
