BROADENING OF RARE EARTH ION EMISSION BANDWIDTH IN PHOSPHATE BASED LASER GLASSES

摘要

Disclosed are the use of phosphate-based glasses as a solid state laser gain medium, in particular, the invention relates to broadening the emission bandwidth of rare earth ions used as lasing ions in a phosphate-based glass composition, where the broadening of the emission bandwidth is believed to be achieved by the hybridization of the glass network.
