Abstract

We report the generation of a collimated hollow beam using a single axicon mirror. The focusing of this hollow beam has been studied using different focusing elements—axicon lens and spherical lens. The results show that if parameters of the focusing lenses are chosen suitably, nearly identical intensity patterns of Bessel beams in the focal region of the lenses can be obtained with two different types of focusing lenses.
