Proceedings ArticleDOI
Efficient Lasers at 1.6-1.8 μm Based on Bismuth-Doped Germanosilicate Fibers with Thermally Induced Active Centers
E. M. Dianov,Sergei V. Firstov,A. V. Kharakhordin,Sergey Alyshev,Konstantin Riumkin,Mikhail Melkumov +5 more
TL;DR: In this paper, an 8.5m long bismuth-doped fiber containing thermally induced active centers was used to achieve a slope efficiency of 18% at the wavelength 1700 nm.
Journal ArticleDOI
Temperature dependences of photoluminescence spectra of single-crystal Ca2GeO4:Cr4+ films
O. N. Gorshkov,E. S. Demidov,E. M. Dianov,A. P. Kasatkin,V. F. Lebedev,G. A. Maksimov,S. A. Tyurin,A. B. Chigineva,Yu. I. Chigirinskii,A. N. Shushunov +9 more
TL;DR: In this paper, the temperature dependence of photoluminescence spectra in the wavelength range of 1.1-1.4 μm was measured at temperatures of 77-573 K in single-crystal Ca2GeO4:Cr+ films deposited onto the (110) surface of a single crystal and studied.
Proceedings ArticleDOI
High-Energy Nanosecond Pulse Delivery Through Singlemode Large Mode Area All-Solid Bandgap Fibres
Sébastien Février,D. Gruppi,Pierre Viale,C. Humbert,Raphaël Jamier,Benoit Beaudou,A. Hirth,Sergey L. Semjonov,Mikhail E. Likhachev,Mikhail M. Bubnov,E. M. Dianov,Vladimir F. Khopin,M.Y. Salganskii,A N Gur'yanov +13 more
TL;DR: In this article, the authors demonstrate that ns pulses with energy up to 0.4 mJ (peak power up to 11kW) can be delivered using all-solid large-mode-area bandgap fiber.
Proceedings ArticleDOI
Lasing features in annealed high-germania-core optical fibers doped with bismuth
Sergei V. Firstov,A. V. Kharakhordin,Sergey Alyshev,Konstantin Riumkin,Vladimir F. Khopin,Mikhail Melkumov,A N Gur'yanov,E. M. Dianov +7 more
TL;DR: In this article, the results on lasing features in annealed bismuth-doped optical fibers were reported and it was found that the annealing fibers present better lasing properties than the pristine ones which contain similar amount of the bismith active centers associated with germanium.
Book ChapterDOI
Photoinduced refractive index change and second harmonic generation in mcvd germanosilicate core fibres fabricated in reduced (nitrogen and helium) atmospheres
E. M. Dianov,A N Gur'yanov,Vladimir F. Khopin,Valery M. Mashinsky,Oleg I. Medvedkov,O.D. Sazhin,Sergei A. Vasiliev,N N Vechkanov,Yu P Yatsenko +8 more
TL;DR: In this article, singlemode germanosilicate-core optical fibres were fabricated by the MCVD process modified by sintering of the deposited soot in a reduced atmosphere (helium- or nitrogen-containing one).
