An epitaxially grown ytterbium-doped gadolinium gallium garnet (Yb:GGG) buried channel waveguide laser is prepared on an yttrium substituted GGG substrate (Y:GGG). The effective light guiding structure is obtained as a result of the difference of refractive indices of Yb:GGG and Y:GGG. The Yb:GGG waveguide exhibits single-mode 1.025 μm lasing operation at room temperature. The incident threshold and slope efficiency of the 5-mm-long waveguide laser when pumped at 0.941 μm are 80 mW and 13.4%, respectively. © 1996 American Institute of Physics.
