In this 4 year project, new optically active phosphate-based glasses and glass-ceramics are developed and drawn into fibers. The glass-ceramics are obtained by adding nanoparticles in the glassy matrix or by controlling in-situ the growth of nanoparticles in the glassy matrix. The main goal of this project is to understand the fundamental effect of the glass/glass-ceramic network on the RE solubility, RE luminescence properties and the material photo-response during lasing. We also plan to demonstrate that it is possible to predict prior to drawing the fibers the stability of the fibers during lasing from the photoresponse of the glass/glass-ceramic. The originality of the project lies in the development of fibers drawn from glass-ceramics. The proposed effort is interdisciplinary and will require know-how in optical glass science, optical and luminescence properties, nucleation and growth, glass-light interaction and fiber technology.
