Adaptively-controlled holographic femtosecond laser processing system
Satoshi Hasegawa, Yoshio Hayasaki (Utsunomiya Univ.) LQE2011-14
Abstract (in Japanese) (See Japanese page) 
(in English) Holographic femtosecond laser processing has the advantages of high throughout and high light-utilization efficiency of a laser pulse energy by shaping the laser pulse into an arbitrary optical intensity pattern with use of a computer-generated hologram displayed on a spatial light modulator. In holographic femtosecond laser processing, an adaptive control of the processing system is important for fabricating enormous numbers of nanometer-scale structures efficiently and precisely. In this paper, we demonstrated an optimization of the hologram and a correction of wavefront aberration in the optical system based on the adaptive control.
