A thulium-doped tantalum pentoxide waveguide laser
A thulium-doped tantalum pentoxide waveguide laser
Tm-doped Ta2O5 films, deposited on thermally oxidized silicon substrates, were etched to form rib waveguides. Optically pumped (793 nm) multimode lasing at 1.9 µm is demonstrated from bare facets, producing 24-mW output, 46% slope efficiency.

Abstract
Tm-doped Ta2O5 films, deposited on thermally oxidized silicon substrates, were etched to form rib waveguides. Optically pumped (793 nm) multimode lasing at 1.9 µm is demonstrated from bare facets, producing 24-mW output, 46% slope efficiency.
