Generation of deep ultraviolet vortices via amplitude and phase spiral zone plates

Year: 2025

Type: article

Abstract: We present the development and experimental implementation of diffractive optical elements designed to generate optical vortices in the deep ultraviolet range (260–266 nm). These elements, fabricated using advanced lithographic and etching techniques, facilitate the efficient transformation of Gaussian beams into twisted modes carrying orbital angular momentum. Experimental tests conducted using the drive laser of an RF photoinjector at JINR successfully demonstrate the generation of deep-ultraviolet optical vortices with a topological charge of l=1. These findings underscore the potential of structured light in the deep ultraviolet range for applications in relativistic electron beam studies and beam manipulation technologies.
