Abstract

Room-temperature, continuous-wave, blue upconversion lasers based on-Thulium-doped fluorozirconate fibre have previously been demonstrated 480 run1 and 450 run2. Here we report .the spectroscopic investigation of photon-avalanche pumping of these blue emissions, which is not reliant on resonant ground-state absorption and so allows new pumping wavelengths.
