Abstract
We report infrared to visible frequency upconversion through a two-pho ton absorption process followed by energy transfer between a pair of P r3+ ions in a silicate fiber. Emission in the blue and red regions of the spectrum are obtained through absorption of infrared photons, desp ite the strong nonradiative decay rates that are characteristic of sil icate fibers. In particular the red emission could be observed by the naked eye possibly due to superfluorescent emission that takes place u nder strong pumping in the infrared.
