22 November 2011Focused Gaussian beam with induced optical vortex movement
The optical vortex is introduced into the incident Gaussian beam by a vortex lens. Then the beam with the
optical vortex is focused by a lens. By changing the position of the vortex lens we can shift the optical vortex
position inside the focused beam. We discussed the relation between vortex lens shift and optical vortex
movement inside the focused beam. The influence of optical system errors on this vortex movement is also
discussed.
