Spectral Broadening of Femtosecond Optical Vortices at Filamentation in Fused Silica under the Conditions of the Anomalous Group Velocity Dispersion
Autor: Sergei V Chekalin, E. V. Vasilyev, Svyatoslav A Shlenov, V. O. Kompanets, R. V. Skidanov
Publikováno v: Journal of Experimental and Theoretical Physics. 132:334-340
Features of the spectral broadening of femtosecond optical vortices at self-action in a medium with the anomalous group velocity dispersion have been studied experimentally and numerically. It has been found that the broadening of the frequency–ang

Autor: V V Podlipnov, N A Firsov, N A Ivliev, S V Mashkov, P A Ishkin, R V Skidanov, A V Nikonorov
Publikováno v: IOP Conference Series: Earth and Environmental Science. 1138:012040
The paper presents the results of a study of the method of classification of vegetation types based on hyperspectral survey data. A hyperspectrometer based on the Offner scheme was used as a shooting equipment. The spatial-spectral architecture of a

Modeling the image obtained by a system of vortex harmonic lenses
Autor: R. V. Skidanov, A. S. Khokhlov
Publikováno v: Journal of Physics: Conference Series. 1745:012025
The possibility of obtaining images using a system based on vortex diffraction lenses is considered. A system of two vortex harmonic lenses was simulated. In the system the total intensity distribution was calculated using the Fresnel transform. The

A dual-range spectrometer based on the Offner scheme
Autor: R. V. Skidanov, V. A. Blank
Publikováno v: Computer Optics. 40:968-971
We considered the feasibility of using a dual-range diffraction grating on the convex mirror in an imaging hyperspectrometer based on the Offner scheme. We conducted modeling in Zemax software. It is shown that the use of a dual-range grating allows

Diffractive optical elements for forming radially polarized light, based on the use stack of stoletov
Autor: R. V. Skidanov, A. A. Morozov
Publikováno v: Computer Optics. 38:614-618
We introduce a new method to obtain the radially polarized light by use of a diffractive axicon and a Stoletov pile. It is shown that using the method proposed it is possible to form radially polarized light beams. A radially polarized light beam is

Hypergeometric modes
Autor: V V, Kotlyar, R V, Skidanov, S N, Khonina, V A, Soifer
Publikováno v: Optics Letters. 32:742
A new family of paraxial laser beams that form an orthogonal basis is discussed. When propagated in uniform space, these beams preserve their structure to scale. The intensity distribution profile for such beams is similar to that for the Bessel mode
