Gaussian laser beam transformation into an optical vortex beam by helical lens
Ljiljana Janicijevic, Suzana Topuzoski
In this article we investigate the Fresnel diffraction characteristics of the hybrid optical element which is a combination of a spiral phase plate (SPP) with topological charge p…
Diffraction characteristics of optical elements designed as phase layers with cosine-profiled periodicity in azimuthal direction
Suzana Topuzoski, Ljiljana Janicijevic
The article concerns an investigation of the Fresnel diffraction characteristics of two types of phase optical elements, under Gaussian laser beam illumination. Both elements provi…
Fraunhofer diffraction of a Laguerre-Gaussian laser beam by fork-shaped grating
Suzana Topuzoski, Ljiljana Janicijevic
In this article we present a theoretical study for Fraunhofer diffraction of a Laguerre-Gaussian laser beam with zeroth radial mode number and azimuthal mode number l by diffractiv…
Fresnel and Fraunhofer diffraction of a laser Gaussian beam by fork-shaped gratings
Ljiljana Janicijevic, Suzana Topuzoski
Expressions describing the vortex beams, which are generated in a process of Fresnel diffraction of a Gaussian beam, incident out of waist on a fork-shaped gratings of arbitrary in…
