Ultra-narrow-linewidth distributed feedback lasers in Al<inf>2</inf>O<inf>3</inf>:Er<sup>3+</sup> and Al<inf>2</inf>O<inf>3</inf>:Yb<sup>3+</sup>
Abstract
The fabrication and characterization of rare-earth-ion-doped monolithic distributed feedback channel waveguide lasers in aluminum oxide are presented. Erbium-doped lasers with linewidths of 1.7 kHz and ytterbium-doped lasers with slope efficiencies of 67% are demonstrated.
