多段阵列式钕玻璃放大器的漫反射器的研究

Study of the multisegment amplifier with diffuse reflector

  • 摘要: 用光线追迹和蒙特卡罗法建立了含有漫反射器的多段阵列式钕玻璃放大器(MSA)的泵浦模型,程序中采用了闪光灯辐射谱和钕玻璃的吸收谱实验数据.模拟结果表明,采用漫反射器可得到高的光传输效率和好的光能量分布均匀性.

     

    Abstract: A numerical simulation model for the multisegment amplifier(MSA) with diffuse reflector has been built up by using ray-tracing and Monte Carlo methods.In our simulation,experimental data of the flashlamp radiation and Nd:glass absorption spectra have been considered.Numerical calculations have been performed,showing that both high transfer efficiency and good pumping energy distribution uniformity can be obtained in the use of the diffuse reflector.
