Abstract

We report on a Yb 3 + -doped sesquioxide waveguide laser based on a lattice-matched Yb 3 + ( 3 % ) : ( Gd , Lu ) 2 O 3 film that has been epitaxially grown on Y 2 O 3 using pulsed laser deposition. Rib-channel waveguides have been structured by reactive ion etching. Laser emission at 976.8 nm was observed under pumping with a Ti 3 + : Al 2 O 3 laser at 905 nm . A laser threshold of 17 mW and a slope efficiency of 6.7% have been achieved with respect to input power. For an incident pump power of 200 mW , a maximum output power of 12 mW could be realized.
