Abstract

Fundamental and higher-order cooperative luminescence emitted from Yb-doped optical fiber (YDF) are observed. Each luminescence is well related to different transition between sublevels of YDF located in the infrared region. Detailed transition properties of YDF are discussed.

Blue and green cooperative luminescence of highly Yb-doped optical fiber

Blue luminescence emitted from ytterbium-doped fiber under infrared excitation was observed, along with well-known green cooperated luminescence. We suggest blue luminescence is due to higher-order cooperated luminescence related three excited ytterbium ions.

The visible cooperative luminescence in Ytterbium-doped optical fibres was observed using a Titanium-Sapphire infrared laser excitation (≈900nm). The evolution of this luminescence as a function of absorbed power is discussed. The optical confinement therefore enables us to observe new saturation effects which are studied for two different Ytterbium fibres.

In search for intrinsic optical bistability in solid-state optical materials, we studied cooperative absorption and emission in Yb3AI5O12, Yb2O3, Yb:Y2O3, Yb:Lu2O3, and Yb:Sc2O3 laser related crystals. The bistability in cooperative luminescence in Yb(6%):ScO3 has been observed.

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

Alexander V. Kir’yanov, Yuri O. Barmenkov, I. Lucio-Martinez +2 more

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 continuous-wave 980-nm pumping is reported. An analysis of the obtained experimental data shows that YF transmission coefficient is notably affected by the presence of Yb(3+) - Yb(3+) ion-pairs in the fibers, especially in heavily-doped ones. The last fact is confirmed by the study of the cooperative luminescence and absorption effects in the fibers, where a detailed inspection of their dependence on Yb3+ concentration is presented. The pairs' effect is shown to seriously modify both the nonlinear character of YF transmission coefficient at lambda = 980 nm and Yb(3+) excited-state relaxation. A modeling of the experimental data is performed, which allows to find the coefficients addressing the pairs' effect in each of YFs under study and, as a result, to fit the experimentally measured dependences of YF transmission coefficient on pump power, fiber length, and Yb(3+) concentration.
