Paper Abstract

In this paper we model and design a composite Yb:YAG/YAG hexagonal disk laser. In this edge-pumped thin disk laser configuration, the pump light incidents from disk edges and propagates through the disk along the zigzag path and repeatedly passes the gain medium, thus improve the pump uniformity and absorption efficiency. At the first we calculate the absorbed pump distribution by ray tracing method; secondly with using the fraction of the absorbed pump density as the heat source, the temperature distribution is simulated by 3D-FEM. Finally the output power is calculated by solving the quasi-three-level system rate equations. The absorption efficiency, the pump uniformity and temperature distribution are three effective parameters on the laser system operation. These parameters are investigated and optimized by this model.
