DESCRIPTION:Prof. Yoshio Hayasaki\, Center for Optical Research and Educat
 ion (CORE)\, Utsunomiya University\nHolographic beam shaping achieved by e
 xploiting the rewritable capability of a spatial light modulator (SLM) dis
 playing a\ncomputer-generated hologram (CGH) is very useful in a variety o
 f applications\, especially material laser processing [1].\nAlthough it pr
 ovides high-processing throughput and high light-use efficiency\, the accu
 racy of the beam shaping is degraded\naccording to static and dynamic impe
 rfections in the optical system. In order to compensate the static imperfe
 ctions\, a\nmethod that performs the optimization of the CGH in the optica
 l system\, called as an in-system optimization\, was developed\n[2\, 3]. A
  further method that allowing it to dynamically compensate for unknown and
  sudden disturbances for continuously\noptimizing a CGH during laser proce
 ssing was developed [4]. Recently\, it was extended to three-dimensionally
  focused\nbeams [5] ...
