Nemoto K, Fujii T, Goto N, Takino H, Kobayashi T, Shibata N, Yamamura K, Mori Y.
PMID: 18250705
Appl Opt. 1997 Jan 20;36(3):551-7. doi: 10.1364/ao.36.000551.

A nonaxisymmetric mirror is designed by the same method as a computer-generated hologram for laser beam intensity profile transformation and is fabricated by plasma chemical vaporization machining. We successfully transformed a circular Gaussian beam of a He-Ne laser into...
