Abstract

The zone plate Talbot interferometer was first used for the visualization of thermal inhomogeneity in the active laser element induced by pumping radiation. A registered moire pattern allows clearly observe of appearance of distortions and its kinetics. The estimations of thermal distortions of refractive index given from experiment are agreed with theoretical calculations.
