Орешонков, А. С. Raman spectra and phase composition of MnGeO3 crystals [Текст] / А. С. Орешонков, Ю. В. Герасимова, А. А. Ершов, А. С. Крылов, К. А. Шайхутдинов, А. Н. Втюрин, М. С. Молокеев, К. Ю. Терентьев, Н. В. Махашенок // Journal of Raman Spectroscopy. — 2016. — Т. 47 (№ 5). — С. 531-536

Аннотация:

MnGeO3 single-crystal samples have been synthesized by optical zonal melting and spontaneous crystallization. X-ray crystal analysis showed the first sample to be a two-phase one with phase ratio as follows: 17% – monoclinic C2/c, and 83%– orthorhombic Pbca; the phase ratio of the second sample was unknown. Raman spectra have been produced for these samples. Lattice dynamics has been simulated and polarization dependencies of lines’ intensities have been analyzed to interpret experimental Raman spectra and to attribute lines to the spectra of monoclinic and orthorhombic phases.

Coherent manipulation of the Raman-induced gratings in atomic media

Arkhipkin, V. G.; Myslivets, S. A. (2016-01)

We consider dynamically controllable periodic structures (gratings), resulting from Raman interaction of a weak probe field with a standing-wave pump and a second control laser field in four-level atomic media of N type. ...
Filamentation Process of Femtosecond Laser Pulse in Air and Associated Phenomena

Prokopev, Vladimir E.; Lubenko, Dmitrii M.; Прокопьев, Владимир Е.; Лубенко, Дмитрий М. (Journal of Siberian Federal University. Сибирский федеральный университет, 2025-06)

The paper presents experimental studies of physical processes and conditions for generate high-directional white-light supercontinuum in visible range. It was shown that it occurs in filamentation area and postfilamentation ...
Raman Spectroscopy Study of the Behavior of the Soft Mode in a Structural Phase Transition in the Pr3Sb5O12 Crystal

Орешонков, А. С.; Ходжибаев, А. К.; Крылов, А. С.; Умаров, М. Ф.; Втюрин, А. Н.; Oreshonkov, A. S.; Khodzhibaev, A. K.; Krylov, A. S.; Umarov, M. F.; Vtyurin, A. N. (2015-11)

The structural phase transition in the Pr3Sb5O12 crystal has been studied using Raman spectroscopy. The phase transition is accompanied by the recovery of the soft mode below T = 735 K, which is associated with the ...
Incommensurately modulated structure and spectroscopic properties of CaGd2(MoO4)4:Ho3+/Yb3+ phosphors for upconversion applications

Лим, Ч. С.; Атучин, В. В.; Александровский, А. С.; Молокеев, М. С.; Орешонков, А. С. (2016-06)

CaGd2(MoO4)4:Ho3+/Yb3+ phosphors doped by Ho3+ and Yb3+ (Ho3+ = 0 and 0.05, and Yb3+ = 0, 0.35, 0.40, 0.45 and 0.50) were successfully synthesized by the microwave sol-gel method. The synthesized particles, being formed ...
