It is shown that in low-concentration erbium-doped silicate fibers (below 1000 p.p.m.), a residual absorption at 980 nm cannot be saturated. Usual models for upconversion of Er/sup 3+/ cannot match this behavior nor explain a fluorescence lifetime independent of pump power and erbium concentration. A phenomenon, the pair induced quenching (PIQ), that is compatible with the previous experimental results is exhibited. The influence of erbium and aluminum concentration on the ion pair proportion is shown. >read more

Upconversion and Anti-Stokes Processes with f and d Ions in Solids
TL;DR: Before the 1960s, all anti-Stokes emissions, which were known to exist, involved emission energies in excess of excitation energies by only a few kT and were linked to thermal population of energy states above excitation states by such an energy amount.

Effects of concentration on the performance of erbium-doped fiber amplifiers
TL;DR: In this paper, the authors studied the dependence of erbium-doped fiber amplifier performance on the ion concentration and found that the quantum efficiency of the amplifier is strongly dependent on ion concentration, signal wavelength, and the relative propagation direction of the pump and signal beams.

Towards rare-earth clustering control in doped glasses
F. Auzel,Philippe Goldner +1 more
TL;DR: In this paper, a new doping principle is proposed based on the recognition that introducing the doping RE into the glass composition through given precursor crystals with large RE-RE distances, allows some control of the clustering of rare-earth ions and of their self-quenching.

Concentration-dependent upconversion in Er/sup 3+/-doped fiber amplifiers: Experiments and modeling
TL;DR: In this article, eight different fibers were studied to examine upconversion as a function of erbium concentration below 1000 ppm by weight, and a computer model of two-particle up-conversion made it possible to estimate the up conversion coefficient used in a rate-equation model.

Pump excited-state absorption in erbium-doped fibers.
TL;DR: It is shown that the host glass influences the excited-state absorption spectra and that P(2)O(5)- or A1(2]O(3)-codoped fibers are the preferred choice for 514.5-, 655-, or 807-nm pump wavelengths owing to reduced pump excited- state absorption.

Pair induced quenching in erbium doped silicate fibers
TL;DR: In high concentration erbium doped fibers (above 0.1 to 0.2%), randomly distributed ion ions are close enough to quench the 4II3/2 level via cooperative upconversion followed mostly by a non radiative deexcitation or less often (≃10-3) by a 980 nm photon emission.
