Paper Abstract

In this paper, we present a novel technique for beam shaping and mode conversion of elliptical laser beams employing vortex phase elements. We show that a vortex phase element with topological charge m=1 can effectively switch between elliptically shaped fundamental TEM00 mode and TEM01 mode. When used with a spatial light modulator, the proposed technique allows beam shape adjustments by applying electrical control signals. Compared to existing static mode conversion techniques, the presented technique may perform dynamic switching between the different laser modes. The developed technique may have several practical applications in the fields of photonics and laser optics, including beam splitters and interferometers, fiber lasers, high speed optical modulators, and optical tweezers.
