Abstract: (774 Views)
In this work, the report of design, preparation and characterization of fork-shaped diffraction gratings with micrometric line spacing is presented. A simple preparation method is proposed and by investigating the preparation parameters, the method is optimized. The used optical setup for generation of optical vortex from the fork-shaped gratings and the obtained results are also presented. The results show that using the proposed method, optimal line spacing is about 175 mm and the obtained grating can produce a good quality optical vortex.
