Spatial beam self-cleaning in tapered Yb-doped GRIN multimode fiber with decelerating nonlinearity
A. Niang, D. Modotto, A. Tonello +12
We experimentally demonstrate spatial beam self-cleaning in an Yb-doped graded-index multimode fiber taper, both in passive and active configurations. The input laser beam at 1064…
On the possibility of mid-IR supercontinuum generation in As-Se-Te/As-S core/clad fibers with all-fiber femtosecond pump source
E. A. Anashkina, V. S. Shiryaev, G. E. Snopatin +2
We propose and optimize theoretically a supercontinuum (SC) laser source in the mid-IR based on using As-Se-Te/As-S core/clad step-index fibers and a femtosecond all-fiber laser sy…
Development of As-Se tapered suspended-core fibers for ultra-broadband mid-IR
E. A. Anashkina, V. S. Shiryaev, M. Y. Koptev +2
We designed and developed tapered suspended-core fibers of high-purity As39Se61 glass for supercontinuum generation in the mid-IR with a standard fiber laser pump source at 2 m.…
Core-clad Pr(3+)-doped Ga(In)-Ge-As-Se-(I) glass fibers: preparation, investigation, simulation of laser characteristics
E. V. Karaksina, V. S. Shiryaev, M. F. Churbanov +3
Core-clad fibers on the basis of high-purity 1300 ppmw Pr(3+)-doped Ga-Ge-As-Se and 2000 ppmw Pr(3+) -doped In-Ge-As-Se-I glasses have been prepared. The minimum optical losses of…
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…
Refractive index spectral dependence, Raman and transmission spectra of high-purity Si, Si, Si, and Si single crystals
V. G. Plotnichenko, V. O. Nazaryants, E. B. Kryukova +7
Precise measurement of the refractive index of stable silicon isotopes Si, Si, Si single crystals with enrichments above 99.9 at.% and a silicon single crystal…
