摘　　要：基于双光束耦合的原理提出了两级相干光放大的方法,这不仅能使两块低质量晶体取得一块高质量晶体所能达到的效果,而且解决了单级放大难以大幅度提高放大倍数的问题,理论分析与实验演示均表明所提方法是可行的。The method of two-stage coherent optical amplification was put forward based on the principle of two-beam coupling. This not only makes it possible that two pieces of low quality crystals can yield the result that one piece of high quality crystal reaches, but also solves the problem that the amplification coefficient can not be greatly increased by means of one-stage amplification. The feasibility of the method was proved by theoretical analysis and experimental demonstration.
