Abstract

The xenon lamp pumping results in an uneven temperature distribution within neodymium glass. This uneven temperature distribution may induce stress birefringence, leading to thermal depolarization and heightened losses in the laser. Identifying the temperature and stress distributions within the material is crucial for accurately predicting the characteristics of beam depolarization. By employing large-diameter neodymium glass as the gain medium and applying the temperature load of the medium in finite element analysis software, the internal stress distribution can be determined. The depolarization distribution of the medium can be calculated theoretically. Although the depolarization distribution of the medium can be calculated theoretically, the thermal depolarization at the four corners of the beam is considerable, with a maximum depolarization of approximately 0.36%. A comparison of the thermal depolarization of neodymium glass across various diameters indicates that the medium diameter is not related to thermal depolarization.
