Spectroscopic techniques to the characterization of rare earth doped glasses

P.Kothari

Rare-earth ions are of interest in several high-tech areas, the two major ones concerning magnetic and optical devices. In the latter field, one can exploit the unique Spectroscopic properties of rare-earth ions to develop novel or advanced lasers and optical amplifiers. Glasses have been known for a long time as a convenient host for rare earths and have been widely used for the fabrication of solid-state lasers. The aim of the present paper is to highlight the spectroscopic techniques to the characterization of rareearth –doped Glasses.
