Optical vortex generation by optical wedge

Proc. SPIE, Vol. 4607, 78 (2002); doi:10.1117/12.455173

Online Publication Date: 16 April 2003

Conference Date: Thursday 10 May 2001
Conference Location: Chernivsti, Ukraine
Conference Title: Selected Papers from Fifth International Conference on Correlation Optics
Conference Chairs: Oleg V. Angelsky
It is experimentally and theoretically studied the generated vortex process by the optical wedge and the optical knife. After those optical transparencies it takes place the birth and death vortices events. By adjusting the slope angle of the transparency and the beam truncation depth, the Gaussian beam may be converted into the singular beam transferring a single vortex.
