摘要
利用边缘光线原理设计了基于非成像反射腔的棒状放大器,采用相同氙灯放电参数和钕玻璃棒尺寸,数值模拟了成像和非成像两种不同反射腔作用下放大器钕玻璃棒的储能密度,并实验研究了小信号增益系数,模拟和实验结果吻合度较高。非成像反射腔具有特殊光学结构,能够反射全部抽运光至钕玻璃棒表面,从而提升光电转换效率,减少废热产生,提高抽运效率和放大器增益性能,使放大器更加高效、经济。
Abstract
Rod amplifier with non-imaging reflector is designed based on the edge-ray principle. Under the same flashlamp electrical power and rod dimensions, the stored energy density and the small-signal gain coefficient of Nd∶glass rod amplifier with non-imaging and imaging reflector are simulated, respectively. The numerical simulated results are consistent with the experimental results. The non-imaging reflector can reflect all the xenon flashlamp rays to the Nd∶glass rod surface, which can enhance the photoelectric conversion efficiency, reduce the generation of waste heat, increase the pumping efficiency and the amplifier′s gain property. This design can achieve considerable cost savings and improve the efficiency of the amplifier.
