Conical refraction healing after partially blocking the input beam [PDF]
, 2008 In conical refraction, when a focused Gaussian beam passes along one of the optic axes of a biaxial crystal it is transformed into a pair of concentric bright rings at the focal plane.

Orbital angular momentum of an astigmatic Hermite-Gaussian beam [PDF]
Компьютерная оптика, 2018 An explicit formula for the normalized orbital angular momentum (OAM) of an elliptical Hermite-Gaussian (HG) beam of orders (0, n) focused by a cylindrical lens is obtained. In modulus, this OAM can be both greater and smaller than n.

Mode-division-multiplexing of multiple Bessel-Gaussian beams carrying orbital-angular-momentum for obstruction-tolerant free-space optical and millimetre-wave communication links [PDF]
, 2016 We experimentally investigate the potential of using ‘self-healing’ Bessel-Gaussian beams carrying orbital-angular-momentum to overcome limitations in obstructed free-space optical and 28-GHz millimetre-wave communication links. We multiplex and transmit

Results in Physics, 2019 We propose a theoretical model for a rotating elliptical Gaussian optical coherence lattice (REGOCL) in oceanic turbulence. It is found that every sub-beam in the REGOCL maintains a controllable rotation within a certain distance, which plays a ...
