Abstract :
A comprehensive computer model has been developed to simulate the plasma kinetics in a high-repetition frequency, discharge-excited He-Sr recombination laser. A detailed rate equation analysis incorporating about 80 collisional and radiative processes, is used to determine the temporal and spatial (radial) behavior of the discharge parameters and the intracavity laser field during the current pulse, recombination phase, and external electrical circuit is integrated over multiple discharge cycles to yield fully self-consistent results. The species population densities predicted by the model are compared with radial and time-dependent Hook measurements determined experimentally for the same set of standard conditions
