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.
