Higher order optical vortices and formation of speckles
Salla Gangi Reddy, Shashi Prabhakar, Ashok Kumar +2
We have experimentally generated higher order optical vortices and scattered them through a ground glass plate that results in speckle formation. Intensity autocorrelation measurem…
Propagation of an arbitrary vortex pair through an astigmatic optical system and determination of its net topological charge
Salla Gangi Reddy, Shashi Prabhakar, A Aadhi +2
We embed a pair of vortices with different topological charges in a Gaussian beam and study its evolution through an astigmatic optical system, a tilted lens. The propagation dynam…
Experimental generation of ring-shaped beams with random sources
Salla Gangi Reddy, Ashok Kumar, Shashi Prabhakar +1
We have experimentally reproduced ring shaped beams from the scattered Laguerre-Gaussian and Bessel-Gaussian beams. A rotating ground glass plate is used as a scattering medium and…
