Abstract

Stimulated emission at 1.663 μ due to a ⁴S_3/2→⁴I_9/2 transition has been observed from Er³⁺ ions in a crystal of YAlO₃. The threshold for pulsed laser action at room temperature was 52 J. Crystalline Stark levels determined from absorption and fluorescence spectra and fluorescence lifetimes of YAlO₃:Er³⁺ are reported.
