CO2 laser-induced crystallization technique can dramatically reduce the duration of glass ceramics formation from hours to seconds in comparison to conventional thermal heat-treatment. Furthermore, a two-step irradiation expedites nano-crystallization, which can reduce scattering loss.
The influence of SiO 2 inter-diffusion into Cr-doped CaO–Al 2 O 3 glass, Ca 2 GeO 4 , and Mg 2 SiO 4 glass ceramics at high temperature is so severe that almost none of Cr 4+ emission can remain. Although the Cr 4+ emission can be recovered up to 13% from its pristine value after re-heat treatment in the initial composition of...
This study investigates the influence of SiO2 on fluorescence properties of Cr-doped glass and glass ceramic. The goal is to develop a novel glass which is resistant to SiO2 interaction during fiber drawing.
