WebUsing the weak nonparaxial approximation, we derive explicit analytical relationships for three projections of the electric field vector of a hypergeometric (HyG) laser beam. For the HyG beams with topological charge n = 0, 1 we derive explicit formulae for the axial intensity, which suggest that the waist position is related to the parameters of the HyG … WebWe derive explicit analytical relations to describe paraxial light beams that represent a particular case of the hypergeometric (HyG) laser beams [J. Opt. Soc. Am. A 25, 262–270 (2008)]. Among these are modified quadratic Bessel–Gaussian beams, hollow Gaussian optical vortices, modified elegant Laguerre– Gaussian beams, and gamma-HyG beams.

Lensless focusing of hypergeometric laser beams

WebOrbital angular momentum (OAM) and topological charge (TC) are key parameters that characterize optical vortex laser beams [].In Laguerre–Gaussian (LG) vortex beams, the normalized-to-power OAM is known to equal the TC, denoted as l [].LG beams, as well as some other familiar vortex beams, including Bessel–Gaussian [], Hypergeometric [3,4], … Webbeams [5], HyG beams [6], and circular beams (CiBs) [7] ensued. Note that the HyG modes [1] and the HyGG beams [5] were produced using liquid-crystal microdisplays. In [5] a … eevee box shinning fates
