Mathematical modeling of ion recombination strontium vapor laser

摘要

In the present work, a self-consistent model of the He-Sr recombination laser is developed. With this model one can calculate plasma parameters and laser characteristics in pulsed-periodic regime and also carry out multiparametric optimization of the laser. The calculations carried out by the model show that under a wide range of conditions (p_(He)= 3 Torr - 3000 Torr) the model allows to trace rather precisely all trends in the behavior of plasma parameters and laser characteristics. The calculations of laser characteristics carried out for 7 active elements with different geometry (l_a = 9 - 70 cm, d = 0.3 - 1.55 cm) show good agreement with experiment. The developed model can serve as a convenient tool for investigating kinetics of the active medium of the He-Sr laser.
