光束组合法是一种很有前途的技术，可用于构造重复频率超过10 Hz的超高能量激光器，如真实的聚变驱动器。在我们以前的工作中，相位控制技术实现这一系统的必要性，提出和实验证明。然而，这些先前的工作是在没有放大器的情况下完成的。本文采用放大器对真实的组束系统进行了测试，在总输出能量为204mJ的5000次（500s）激光照射中，获得了λ scin51标准差起伏的稳定相位控制。
The beam combination method is the promising technique for constructing a very high energy laser with a high repetition rate over 10Hz such as a real fusion driver. In our previous works, the phase control technique essential for realizing this system was proposed and demonstrated experimentally. However, these previous works were done without amplifiers. In this work, we employed amplifiers to test the real beam combination system and obtained a well stabilized phase controlling with λ∕51 fluctuation by standard deviation during 5000 laser shots (500s) at 204mJ total output energy.
