Consideration and Evaluation of Factors Influencing the Stimulated Optical Scattering in Gases

Abstract

In the presence of intense laser beams, the normally weak raman and brillouin scattering from materials can become stimulated. The customary theory predicts that the intensity of the scattered stokes were grows exponentially with distance at fixed laser power. This report presents the results of numerical calculations of the gain factor for the important scattering mechanisms in several diatomic gases as functions of temperature and pressure. Competition and transitions between various stimulated processes are predicted as functions of pressure and temperature. Some experimental data are presented to indicate that it is in general agreement with the simple theory. The experimental verification of the crossing over between processes and indications of the competition near the crossover are also presented.
