摘要
采用光线追迹和蒙特卡罗法以及实验拟合数据,建立了多段钕玻璃放大器闪光灯泵浦腔的数值计算模型。模拟结果表明,光传输效率、储能密度分布和泵浦均匀性与泵浦腔几何构形有关。提出了一种新泵浦腔构形,它具有效率高、均匀性好和造价不很高的优点。
Using the ray tracing and Monte Carlo as well as the experimental fitting data, we present a numerical simulation model for pumping cavities of the multisegment Nd∶glass amplifier. The simulation shows that the transfer efficiency, stored energy density distribution and uniformity of the pump radiation are dependent on the pumping cavity geometry. A novel pumping cavity is proposed, which demonstrates advantages of the high efficiency, good uniformity and tolerable cost. The results obtained are useful for the design of the large scale multisegment Nd:glass amplifier.
