NUMERICAL AND ANALYTICAL APPROACHES TO LASING PROCESSES IN SOME ACTIVE GASEOUS MEDIA

摘要

Some solutions of analytical and numerical tasks in laser physics are given. As active material, gaseous media are chosen (atomic and molecular cases like HF). The laser gain and linewidth dependencies vs. different parameters, were considered. Starting from generalized (for example Voigt line form) presentation, contributions of Dopplcr as well as collision processes to the line broadening were analyzed. Earlier developed algorithms for molecular dynamics had to be considered from the point of view of new computer architectures and requests for stimulated emission.
