Paper Abstract

High-power laser radiation propagating in molecular gases strongly affects both the optical characteristics of the medium in the channel of propagation (the absorption coefficient and the index of refraction) and the characteristics of the laser radiation self-action in resonance- absorbing molecular gases. These effects in the atmosphere are of great current interest for atmospheric optics. Over the long atmospheric paths, even comparatively weak nonlinear effects may have significant impact on propagation of high-power radiation. The present paper deals with the results of studying the nonlinear spectroscopy of atmospheric gases and the problems of accounting for nonlinear effects for solving the problems of atmospheric optics.
