20 September 2005 Ultraviolet emission from praseodymium doped fibers
Author Affiliations +
Optical spectra of Pr3+ doped fiber was recorded under dye laser and Ar+ laser excitation. Fluorescence was observed from 1D2 and 3P0 levels. In addition to that emission was also observed at 280 to 300 nm due to cooperative emission.
