Results  of a comprehensive investigation  of a thermally 
stressed state and optical quality  of a cylindric active 
medium of  a high-power  solid-state laser are presented. 
A comparative  analysis of the effects of the temperature
-induced  gradient of the refractive  index, variation of 
the shape of the active medium, and induced birefringence 
is carried out.
