Single-pass, nonlinear frequency conversion of full Poincaré beams
K. Subith, Ravi K. Saripalli, Anirban Ghosh +1
Full Poincaré (FP) beams, a special class of fully correlated beams generated through the coaxial superposition of a Laguerre-Gauss and fundamental Gaussian modes of orthogonal pol…
Controlled generation of array beams of higher order orbital angular momentum and study of their frequency doubling characteristics
B. S. Harshith, G. K. Samanta
We report on a simple and compact experimental scheme to generate high power, ultrafast, higher order vortex array beams. Simply by using a dielectric microlens array (MLA) and a p…
Single-pass, second harmonic generation of ultrafast, higher order vector vortex beams at blue
Ravi Kiran Saripalli, Anirban Ghosh, N. Apurv Chaitanya +1
We report a novel experimental scheme for single-pass second harmonic generation (SHG) of vector vortex beam in the blue. Using an ultrafast Ti:Sapphire laser of pulse width ~17 fs…
Simultaneous generation of high power, ultrafast 1D and 2D Airy beams and their frequency doubling characteristics
Raghwinder S. Grewal, Anirban Ghosh, G. K. Samanta
We report on a simple experimental scheme based on a pair of cylindrical lenses (convex and concave) of same focal length and common optical elements producing high power optical b…
Controlling the biphoton orbital angular momentum eigenmodes using asymmetric pump vortex beam
M. V. Jabir, Ali Anwar, G. K. Samanta
We report on controlling the bi-photon orbital angular momentum (OAM) eigenmodes in the spontaneous parametric down conversion process by simply adjusting the asymmetry of the pump…
Controlled generation, manipulation and frequency conversion of broadband orbital angular momentum spectrum of asymmetric optical vortex beams
Sabir Ul Alam, A. Srinivasa Rao, Anirban Ghosh +2
We report on generation and control of tunable, broad orbital angular momentum (OAM) spectrum of a vortex beam. Using two spiral phase plates (SPPs), we have converted the Gaussian…
