钕玻璃片状激光放大器中氙灯几何参数优化的热效应仿真

Based on a multi -physics coupled numerical simulation approach, this study systematically investigates the influence of xenon lamp geometric parameters on the temperature field and thermal stress in a side -pumped neodymium glass slab.A coupled TracePro and Ansys model is employed to accurately simulate non -uniform pump absorption and quantify thermal gradients and stress distributions under different parameter settings.The results reveal that increasing the lamp inner diameter improves pump uniformity, adding more lamps leads to linear heat accumulation, and the optimal xenon lamp spacing ranges from 7 mm to 9 mm.This research provides an important basis for the optimized design of pump sources in high -power laser systems.
