The thermal lens calculated by numerical calculations plays a significant role in the non-planar ring oscillator (NPRO). And the temperature, strain, and face bugling required for the calculation are obtained by finite element analysis methods. According to the finite element analysis, we can easily know that the maximum temperature of the crystal is 306.5K and the maximum thermal strain is 1.0E-4 with 3W pump power. What most important in the optical path difference analysis is the thermal lens induced by temperature. In this work, we provided the data for studying the influence of thermal lens on loss difference and made the thermal model refined, which is the basis for an optimized resonator design with high power and narrow linewidth seed light source systems.
