An experimental and theoretical investigation of the nonlinear transmission coefficient in a
set of Ytterbium-doped silica fibers (YFs) with various concentrations of Yb^ 3+ ions at …

Infrared transmission and Raman scattering have been used to study Raman active
phonons and crystal-field excitations in Yb 3+-doped yttrium, lutetium and scandium …

Using a scalar crystal field parameter, we show that the maximum splitting of 2F7/2 of Yb3+
can be quantitatively derived in a theoretical way from the maximum experimental splitting of …

Yb3+/Tb3+/Er3+-doped transparent alkaline earth fluorosilicate glass ceramics containing
SrF2 nanocrystals were prepared and their microstructures and spectroscopic properties …

Abstract Borotungstate phosphors Gd 2-2x Yb 2x (B 2 WO 9)(x= 0, 0.05, 0.1, 0.15, 0.20, 0.25,
0.30) were synthesized using a straightforward high-temperature solid-state reaction …

GdVO 4 single crystal co-doped with Yb 3+ and Er 3+ was grown by the Czochralski method.
The X-ray powder diffraction pattern of Yb, Er: GdVO 4 crystal confirms that the as-grown …

In this paper we present results on cooperative luminescence performed on Yb 3+-doped
metaphosphate glasses under 980 nm excitation. We have measured emission spectra and …

A modeling of an all‐fiber self‐Q‐switched Erbium laser is developed, implying that the
mechanism of self‐Q‐switching is the power‐dependent thermo‐induced lensing in Erbium …

Using the scalar field parameter Nv, calculated from the respective Bkq parameters given in
the literature for 115 different crystals, we show that a simple linear relationship between the …

The preparation and upconversion luminescence properties of the Yb 3+ and Tb 3+ co-
doped glass ceramics containing SrF 2 nanocrystals were investigated. The formation of SrF …
