Abstract: (2103 Views)
Various methods have been developed for construction of the Bessel beam. One of the simplest methods is generating an annual distribution of light. In this paper, an experimental method for the production of Bessel beam using a lithographic mask based on azo methyl red-doped liquid crystal is presented. In order to obtain the best result, a 532nm laser was used to recording the pattern. According to observation, by applying the electric field to the liquid crystal cell for linearly polarized light, the Bessel beam was produced.
