Abstract

We report on what we believe to be the first demonstration of an Er:Sc₂0₃ laser emitting in the 1.6 urn region. Previous attempts to realise this laser have not been successful [1] due to concentration quenching of the fluorescence lifetime of the ⁴I_13/2 level caused by upconversion processes. To avoid this detrimental effect, our crystals had very low dopant concentrations.
