摘　　要：晶体拼接技术能够解决光参量啁啾脉冲放大(OPCPA)过程中非线性晶体口径受限问题,从而有效地提高放大器的输出能力。晶体加工误差补偿是晶体拼接要解决的核心问题之一。对拼接晶体加工误差对光束质量的影响进行了分析,设计了拼接晶体加工误差补偿方案,设计并加工完成拼接晶体加工误差补偿能动反射镜。通过实验验证了拼接晶体加工误差补偿方案的可行性和稳定性,同时证明了该系统满足晶体拼接要求。Tiling crystals technology can solve the problem of nonlinear crystal aperture limit in the process of optical parametric chirped pulse amplification （OPCPA）. The crystal machining error compenstation is one of the most important problems need to be solved in crystals tiling. The beam quality influenced by tiling crystals machining error is analyzed and the machining error compensation method of tiling crystals is designed. According to the method, an active array mirror system is designed and machined, which is used to compensate the tiling crystal machining error. The feasibility and stability of tiling crystal machining error compensation system is tested, which indicates that the system can satisfy the crystal tiled requirement.
