Analysis of Yb:YAG thin disk laser resonator considering thermal lens effects: Experimentally and by Laser Cavity Analysis and Design
Source abstract
Abstract
In this paper, a precise calculation of thermal lensing effects of a face-pumped Yb:YAG thin disk is presented. First, in a V-shaped resonator, the spatial profiles of pump power on disk active medium at different pump powers were recorded. Then the results were used to examine the three dimensional changes of refractive index and their effects on output power and beam quality through Laser Cavity Analysis and Design software. Finally, the experimental results of M2 and output power measurements were compared with theoretical simulations.
