摘　　要：基于双光束耦合的原理提出了三级相干光放大的方法 ,这不仅能使 3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 ,理论分析表明所提方法是可行的。Based on the principle of two-beam coupling,the method of three-stage coherent optical amplification is put forward.Which not only makes it possible that tress pieces of low quality crystals can yield the result that one piece of high quality crystal can reach,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 has proved through theoretical analysis.
