INFLUENCE OF PHYSICAL PROCESSES IN ACTIVE MEDIUM ON OPTICAL RESONATOR PARAMETERS OF GAS DISCHARGE LASERS

Based on the use of the stationary generation equation, an expression is obtained that relates the dependence of the output power of the laser radiation on parameters determined by physical processes occurring in its active medium: reinforcement and absorption index of the active medium, length of the active medium of the laser, loss of radiation in the optical resonator. The method of creation of function of normalized power of radiation of the laser and also stay on its basis of optimum coefficient of transmission of the working mirror corresponding to the maximum power at the set parameters of the active environment and the optical resonator is developed. Besides, the technique allows defining dependences of optimum coefficient of transmission of a working mirror and efficiency of the optical resonator on parameters of the active environment and the resonator of the laser. A computer program has been developed that makes it possible to optimize the optical resonator parameters in an automated mode. The program has undergone approbation, and can be used at design and development of gas-discharge lasers.
