[23a-13M-10]Optimization of computer-generated hologram under adaptive aberration correction in holographic laser processing machine

〇Koichi Takahashi¹, Satoshi Hasegawa¹, Yoshio Hayasaki¹ (1.Utsunomiya Univ.)

Keywords:

holographic femtosecond laser processing,computer-generated holography,adaptive optics

In this research, in order to achieve high-throughput and high-definition femtosecond laser processing, during beam shaping in holographic laser processing, adaptive optics and in-system optimization of CGH is used to reduce the wavefront distortion caused by optical elements such as SLM and the processing environment.
