High order perfect optical vortex shaping

WebNov 15, 2024 · The concept of a perfect optical vortex (POV) beam was first proposed by Ostrovsky et al. in 2013 [18]. It is a pure aura whose dark hollow radius does not depend on topological charge. In 2014, an improved technique based on the width-pulse approximation of the Bessel function was proposed to generate POV beams [19].
