Title :
Generation of Doughnut-Like Beams by Means of a W-axicon Resonator with a Movable Axicon Element
Author_Institution :
Dept. of Phys., Tokai Univ., Kanagawa
Abstract :
An optical resonator that generates doughnut-like laser beams is fabricated. A w-axicon with a movable center axicon enables us selecting any one of the Laguerre-Gaussian modes oscillation. Oscillation with a dye is demonstrated
