Intense blue upconversion emission has been observed at room temperature under excitation in the range of 630 - 660 nm in a fluoroindate glass doped with 2.5 mol% of Tm3+ . The experimental dynamics and power dependence of this emission are well described using a photon avalanche model based on the mean field approximation.
