The compositions, properties and concepts of the structure of fluoroindate glasses are
considered. These glasses are characterised by low phonon energies and hence very low …

We report on efficient frequency upconversion in Er 3+-doped fluoroindate glass. The
process is observed under 1.48 μm laser diode excitation and results in fluorescence …

Compositional dependence of optical properties of Nd3+ ions are investigated in the
following lithium borate (LBO) glasses: Li2CO3+ H3BO3 and MCO3+ Li2CO3+ H3BO3 (M …

Spectroscopic and physical properties of Nd3+ doped sodium lead flouro-and chloro-borate
glasses of the type 20NaX–30PbO–49.5 B2O3–0.5 Nd2O3 (X= F and Cl) have been …

Multiphonon assisted frequency upconversion was observed in a Nd 3+-doped fluoroindate
glass pumped at 866 nm. A near-infrared upconverted emission at 750 nm with a peculiar …

We propose that Dy/sup 3+/-doped chloride crystals be considered as candidates for
amplification of the 1.3/spl mu/m signal used by the telecommunications network. While …

We have observed ultraviolet upconversion fluorescence from the 4D3/2 and 2P3/2 levels of
Nd3 in fluoroindate glass under infrared pumping. It was found that the excitation of a large …

High purity (GeS2) 80− x (Ga2S3) 20· xPrCl3 (x= 1, 2, 3),(GeS2) 79 (Ga2S3) 20Pr6O11
glasses were prepared and their basic thermal and optical properties were detemuned. The …

Laser action has been predicted in neodymium-doped zinc chloride borophosphate glasses
with the help of laser parameters for the transitions 4F3/2→ 4I9/2, 4F3/2→ 4I11/2 and …

Changing the sample's temperature from 200 K to 535 K, we observed 670-fold
enhancement of a phonon-assisted upconversion emission at≈ 754 nm obtained from a Nd …
