Abstract

When an erbium-doped fluoride fiber was pumped with a red dye laser beam that resonantly excites the F49/2 state, we detected efficient violet upconversion emission from the P23/2 state that is much stronger than the green upconversion emission from the S43/2 state. Such unusual violet emission was found to be due to a three-photon excitation process.
