Polarization dependent gain in neodymium and Ytterbium doped fiber amplifiers.
Optics express, 2003Co-Authors: Peter Weßels, Carsten FallnichAbstract:We present comparative measurements of polarization dependent gain in neodymium and Ytterbium doped fiber amplifiers. It is demonstrated, that this effect is always present in neodymium doped fiber amplifiers while under appropriate operation conditions it can be suppressed in Ytterbium doped fiber amplifiers.

preventing photodarkening in Ytterbium doped high power fiber lasers correlation to the uv transparency of the core glass
Optics Express, 2008Co-Authors: M. Engholm, L. NorinAbstract:Photodarkening experiments are performed on Ytterbium-doped silicate glass samples. A strong charge-transfer (CT) absorption band near 230nm in aluminosilicate glass is found to be correlated to the mechanism of induced color center formation. Excitation into the CT-absorption band generates similar color centers as observed in Ytterbium-doped fiber lasers under 915nm high power diode pumping. The position of the CT-absorption band is compositional dependent and is shifted to shorter wavelengths in Ytterbium doped phosphosilicate glass. Very low levels of photodarkening is observed for the Ytterbium doped phosphosilicate glass composition under 915nm high power diode pumping. Possible excitation routes to reach the CT-absorption band under 915nm pumping are discussed.

Divalent Ytterbium in Ytterbium Doped Aluminosilicate Glass - Aspects on Photodarkening in Fiber Lasers
2007 Conference on Lasers and Electro-Optics (CLEO), 2007Co-Authors: M. Engholm, L. NorinAbstract:We show that divalent Ytterbium ions are present in Ytterbium doped aluminosilicate glass. The presence of Yb2+-ions may influence the formation of induced color centers in Ytterbium doped fiber lasers leading to reduced performance.

cooperative luminescence and absorption in Ytterbium doped silica fiber and the fiber nonlinear transmission coefficient at λ 980 nm with a regard to the Ytterbium ion pairs effect comment
Optics Express, 2006Co-Authors: Rudiger Paschotta, A C TropperAbstract:Recently, significant power losses in Ytterbium-doped fibers have been interpreted as resulting from the formation of Ytterbium ion pairs [A. V. Kir’yanov et al., Opt. Express 14, 3981 (2006)]. However, there appears to be strong evidence against this model.

Ytterbium (III) Luminescence in m-Methylbenzoic Acid-Containing Compounds.
Journal of fluorescence, 2015Co-Authors: I. V. Kalinovskaya, A. N. ZadorozhnayaAbstract:Complex compounds of Ytterbium(III) with m-methylbenzoic acid and nitrogen–containing ligands luminescent in near infrared range have been synthesized. Spectral luminescence characteristics of heteroligand compounds of Ytterbium(III) have been investigated. It has been established that Ytterbium (III) m-methylbenzoate with 1,10–phenanthroline is characterized by the highest luminescence intensity.
