利用非均匀掺杂的设计思想,针对正面抽运、背面冷却的有源反射镜放大器结构中不同激活离子掺杂分布的介质进行了模拟计算,分析并比较了传统均匀掺杂介质与非均匀掺杂放大介质中的温度、温度梯度、应力、应变以及波前畸变的分布。结果表明,与传统均匀掺杂介质相比,非均匀掺杂放大介质内的温度、温度梯度、应力、应变与波前畸变均有明显的降低。模拟结果证明,非均匀掺杂可以改善有源反射镜放大器构型冷却与产热异面的问题,可以有效地提高放大器增益介质热管理性能,为进一步讨论基于非均匀掺杂的放大介质的热管理优化提供了基础。 Using the non-uniform doping design idea, the different active ion doping mediums in active mirror amplifier with front-end pumping and back-side cooling are simulated and compared. The results show that the traditional homogeneous doping media and non-uniform doping media Temperature, Temperature Gradient, Stress, Strain and Wavefront Distortion Distribution in a Hybrid Amplifier. The results show that the temperature, temperature gradient, stress, strain and wavefront distortion in the non-uniform doped media are significantly lower than that of the conventional uniform doping media. The simulation results show that the non-uniform doping can improve the configuration cooling and heat generation of the active mirror amplifier, which can effectively improve the thermal management performance of the amplifier gain medium. In order to further discuss the heat of the amplifier medium based on heterogeneous doping Management optimization provides the foundation.
