Abstract:   (1958 Views)
In this paper a Yb:YAG thin disk laser was studied numerically and the effects of multi-pass pumping and medium temperature in optical efficiency were investigated. The temperature of the medium is considered to be uniform and assuming a plane wave model for pump and laser beam propagation.The equations weresolved by RungeKutta method and shooting method was used to find an initial guess. The temperature dependence of the Boltzmann occupation factors, absorption cross section and emission cross section were included in the calculations. The influence of the number of pump beam passes, doping concentration, crystal thickness and temperature of the crystal on the optical efficiency were investigated.
Keywords: Thin disk laser, Rate equations, Runge Kutta method, Shooting method.
