Simulation of thin disk laser pumping process for temperature dependent Yb:YAG property

A novel model of Cw diode pumped Yb:YAG thin disk laser has been presented to simulate absorption pump power distribution by Monte-Carlo ray tracing. Comparing obtained results with the common distribution function indicate the offered model is quite trustful. So these findings help to evaluate temperature distribution due to the 3D finite element analyses (FEA) based on heat conduction equation. To improve our simulation the temperature dependent of crystal property such as the absorption coefficient, thermal conductivity, stimulated emission cross section and Boltzman population factors are considered by a numerical iterative approach.
