Abstract
When a praseodymium doped fluoride fiber was pumped with a 587 nm dye laser that resonantly excited the 1D2 level of Pr3+, we detected energy upconversion signals at 492 and 522 nm from the 3P0,1 levels. We also observed violet upconversion signals at 356, 382 and 413 nm. Anti Stokes Raman signals were observed at 3500 - 4200 cm-1 away from the laser beam.
