Abstract

Compact sources of short wavelength laser light are required for such diverse applications as laser-induced-fluorescence instrumentation, graphic arts, microscopy, and optical storage. Visible fiber lasers based on rare-earth-doped fluoride glass fibers have produced up to hundreds of milliwatts of red, orange, green or blue light when pumped by infrared lasers — usually Ti:Sapphire. Only recently have diode pumped upconversion fiber lasers been reported.^1,2,3
