We report on the continuous-wave and passively Q-switched waveguide laser at the wavelength of similar to 1024 nm, based on the (Yb0.1Y0.9)(3) (Sc1.5Ga0.5) Ga3O12 (Yb:YSGG) crystal. The ridged waveguide was fabricated on the surface of 100 at% Yb: YSGG crystal by the swift ion irradiation and the precise diamond blade dicing. Utilizing this waveguide as the gain medium and resonant cavity, the laser emission at similar to 1024 nm was realized. Coating the tungsten disulfide onto the waveguide surface as the saturable absorber, the Q-switched laser emission was also obtained with the pulse duration of 125 ns.
