Paper Abstract

Self-consistent theoretical model and computer code for the simulation of the control of atmospheric transmission by means of high-power IR lasers are presented. High-resolution nonequilibrium absorption spectra of the atmosphere are simulated and analyzed. The results of calculations are presented illustrating a number of effects accompanying propagation of intense IR radiation in the atmosphere: negative absorption caused by the inversion of CO2 and H2O levels populations: laser-induced absorption; laser- induced shift of transmission microwindows; explosive-like absorption. The indicated phenomena may for a basis for new methods of remote sensing of the atmosphere.
