The design optimization and experimental investigation of the 4420 nm Raman laser based on hydrogen-filled revolver silica fiber
A. N. Kolyadin, M. S. Astapovich, A. V. Gladyshev +6
Optical properties of hollow-core revolver fibers are numerically investigated depending on various parameters: the hollow-core diameter, the capillary wall thickness, the values o…
Efficient 4.42 μm Raman laser based on hollow-core silica fiber
Maxim S. Astapovich, Anton N. Kolyadin, Alexey V. Gladyshev +5
In this paper we consider mid-infrared Raman lasers based on gas-filled hollow-core silica fibers and provide theoretical and experimental analysis of factors that limit the effici…
Absorption and emission cross section of Yb3+ ions in Al2O3 and P2O5 doped fibers
M. A. Melkumov, I. A. Bufetov, K. S. Kravtsov +2
The results of measurements of the emission and absorption cross section for the transition 2F5/2 -> 2F7/2 of Yb3+ ions in Al2O3 and P2O5 doped silica fibers are presented. Differe…
Thermal behavior of NIR active centers in Bi-doped optical fibers
D. A. Dvoretsky, I. A. Bufetov, V. V. Vel'miskin +6
The temperature dependences of optical loss and luminescence spectra have been measured in visible and NIR spectral range for Bi-doped silica and Bi-doped germanosilicate fibers fo…
IR Bismuth active centers in optical fibers: Combined excitation-emission spectroscopy
S. V. Firstov, V. F. Khopin, I. A. Bufetov +3
3D excitation-emission luminescence spectra of Bi-doped optical fibers of various compositions were measured in a wide wavelength range 450-1700 nm. Such luminescence spectra were…
