Abstract

In this talk, we propose and demonstrate the process-oriented adaptive optics wavefront control method, for optimizing the beam quality in the multi-pass amplifiers. Different from the conventional target-oriented wavefront control approach, the novel method divides the aberration correction process into several steps, to optimize the wavefront quality in time during the courses of the beam's transport and amplification. The experiments validate that the novel approach can effectively prevent the beam quality from worsening and ensure the successful reality of multi-pass amplification.
