Mode matching in the field speckle pattern after graded-index fibers
A. Volyar, M. Bretsko, Ya. Akimova +1
We have developed and implemented a new technique of parallel information transmission through a multimode graded-index fiber in real time based on the approach of intensity moment…
Fine structure of perturbed Laguerre-Gaussian beams: Hermite-Gaussian mode spectra and topological charge
A. Volyar, E. Abramochkin, Yu. Egorov +2
We found that small perturbations of the optical vortex core in the Laguerre-Gaussian (LG) beams generate a fine structure of the Hermite-Gauss (HG) mode spectrum. Such perturbatio…
Digital sorting perturbed laguerre-gaussian beams by radial numbers via high order intensity moments
A. Volyar, M. Bretsko, Ya. Akimova +1
Thus, the results of our studies lie in developing and implementing the basic principles of digital sorting the Laguerre-Gauss modes by radial numbers both for a non-degenerate and…
Orbital angular momentum and informational entropy in perturbed vortex beams
A. Volyar, M. Bretsko, Ya. Akimova +1
We theoretically and experimentally investigated transformations of vortex beams subjected to sector perturbations in the form of hard-edged aperture. The transformations of the vo…
The avalanche instability of the orbital angular momentum in combined vortex beams
A. Volyar, M. Bretsko, Ya. Akimova +1
We presented a new method for measuring the squares of the amplitudes and phases of partial vortex-beams in a complex beam array in real time. The method is based on measuring the…
Measurement of the vortex spectrum in a vortex-beam array without cuts and gluing of the wavefront
A. Volyar, M. Bretsko, Ya. Akimova +1
We presented a new method for measuring the squares of the amplitudes and phases of partial vortex-beams in a complex beam array in real time. The method is based on measuring the…
The mutual transformations of fractional-order and integer-order optical vortices
C. N. Alexeyev, Yu. A. Egorov, A. V. Volyar
We consider the problem of singular beams in optics as a part of the general questions of interactions, shaping and transformations of vortex states with fractional topological cha…
Super pulses of orbital angular momentum in fractional-order spiroid vortex-beams
A. V. Volyar, Yu. A. Egorov
We consider optical properties of Hypergeometric-Gaussian beam compositions with spiral-like intensity and phase distributions that were called the spiroid beams. Their orbital ang…
Optic detectors calibration for measuring ultra-high energy extensive air showers Cherenkov radiation by 532 nm laser
Stanislav Knurenko, Yuri Egorov, Igor Petrov
Calibration of a PMT matrix is crucial for the treatment of the data obtained with Cherenkov tracking detector. Furthermore, due to high variability of the aerosol abundance in the…
Mass Composition Working Group Report at UHECR-2012
E. Barcikowski, J. Bellido, J. Belz +6
We present a summary of the measurements of mass sensitive parameters at the highest cosmic ray energies done by several experiments. The Xmax distribution as a function of energy…
Quadrefringence of optical vortices in a uniaxial crystal
T. Fadeyeva, A. Rubass, Yu. Egorov +2
The splitting of a single optical vortex into four separate ones in a singular beam is theoretically and experimentally described for the propagation of light obliquely through a u…
