Abstract

A detailed modeling of thermal lensing in a microchip Nd:YAG laser is presented. A range of different pump spot sizes as well as pump power levels was explored to determine their effect on thermal lensing, cavity stability and mode-matching was explored. Optimum pump focusing and pump power level conditions were estimated and were shown to strongly depend on the pump focusing condition. This can be used as an additional degree of freedom for optimization of microchip lasers. These results can enable power scaling of microchip lasers.
