Quasi regenerative amplifier of high energy output
-
摘要: 在对再生放大系统进行改进的基础上提出类再生放大技术，应用大口径放大器，在腔内增加完全成像系统，对注入整形光束进行任意多次的保形放大。可行性验证实验基于两个低增益、大口径放大器，已达到大于104的系统增益；在注入能量仅为43 J能量条件下，实现了大于600 mJ的系统输出能量。验证实验结果表明基于较低增益放大器单元的类再生放大系统，既能实现高增益又能实现大能量输出。Abstract: Quasi regenerative amplifier is put forward, which is based on the improvement upon the regenerative amplifier. In the amplifying system, the large-aperture amplifiers are used and the beam is imaged in the amplifier to keep the shape of the beam in the course of amplifying. Experiments on the feasibility of this amplifying concept show that this kind of amplifying system even based on low-gain amplifiers can achieve high system gain and can output high-energy pulses.
