A partial polarization of luminescence in laser phosphate and silicate erbium-doped glasses was found to take place for the fundamental laser transition 4 I 13/2→4 I 15/2 (λ=1.55 μm) under excitation by linearly polarized laser radiation (532 and

Non-linear upconversion quenching in highly Er-doped glasses has been studied with use of Monte-Carlo modeling and a new experimental steady-state technique. The experimental and simulated results exhibit that the upconversion coefficient depends on

The influence of the main components (SiO2, Al2O3, ZnO, and Na2O) of a photothermorefractive glass matrix and Br–ions on the change in the refractive index is studied in the course of photothermoinduced crystallization in glasses. The optimum conce

The partial polarization of luminescence in phosphate and silicate erbium glasses in the range of 1.5 μm under the stimulation by the linearly polarized laser light (532 nm, 790-990 nm) has been detected. The degree of polarization depends both on a

A steady-state method was used for characterization of up-conversion quenching in Er-doped glasses. This method is based on measurement of pumping dependencies of quantum yield and the population of the 4 I 13/2 metastable manifold. The population wa
