Blue avalanche upconversion in Tm:ZBLAN fibre

Blue avalanche upconversion in Tm:ZBLAN fibre
Blue avalanche upconversion in Tm:ZBLAN fibre
We report the investigation of the photon avalanche effect in heavily doped Tm:ZBLAN fibre at room temperature. Pumping at 630nm to 650nm, which is not resonant with the ground state absorption, gives intense blue emissions at 450nm and 480nm. The time evolution of the absorption and emission show a slow decaying oscillation before steady state is reached.

Abstract

We report the investigation of the photon avalanche effect in heavily doped Tm:ZBLAN fibre at room temperature. Pumping at 630nm to 650nm, which is not resonant with the ground state absorption, gives intense blue emissions at 450nm and 480nm. The time evolution of the absorption and emission show a slow decaying oscillation before steady state is reached.
