The beam combination method is the promising technique for constructing a very high energy laser with a high repetition rate over 10 Hz 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 (500 s) at 204 mJ total output energy.
