Autor: A. P. Porfirev, S. N. Khonina, P. A. Khorin, N. A. Ivliev
Publikováno v: Optics letters. 47(19)
Laser patterning of thin films of materials is widely used for the fabrication of one-, two- and three-dimensional functional nanomaterials. Using structured laser beams with a complex structure of amplitude, phase, and polarization distributions all

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

Two-step maskless fabrication of compound fork-shaped gratings in nanomultilayer structures based on chalcogenide glasses
Autor: A. Prisacar, E. Achimova, Vladimir Abashkin, Vladimir V. Podlipnov, Alexey P. Porfirev, N. A. Ivliev, Svetlana N. Khonina, A. Meshalkin
Publikováno v: Optics letters. 46(13)
We demonstrate an easy two-step maskless method for the fabrication of so-called compound fork-shaped gratings in nanomultilayer structures (NMLSs) based on chalcogenide glasses. Such elements allow one to generate different configurations of optical

Analysis of characteristics of paraxial vector Gaussian beams affecting the formation of microstructures in an azopolymer
Autor: Sergey I. Kharitonov, S. G. Volotovskiy, N. A. Ivliev, Vladimir V. Podlipnov, Svetlana N. Khonina
Publikováno v: Компьютерная оптика, Vol 43, Iss 5, Pp 780-788 (2019)
The paper considers paraxial Gaussian laser beams with different polarization states and their characteristics, such as the Poynting vector, gradient force, and force density, which are important for evaluating the effects of radiation on matter. An

Experimental investigation of the stability of Bessel beams in the atmosphere
Autor: V. S. Vasilyev, A. I. Kapustin, N. A. Ivliev, Vladimir V. Podlipnov, Roman V. Skidanov, S. V. Ganchevskaya
Publikováno v: Компьютерная оптика, Vol 43, Iss 3, Pp 376-384 (2019)
We described an experiment on passing Bessel beams through the atmosphere with heat-trolled flows. We showed that at small distances, while passing through the region with a hot air flow, the Bessel beam can be distorted to a complete loss of the str
