Abstract
In this paper, a mirrorless Yb3+-doped KY1-x-yGdxLuy(WO4)2 waveguide laser with cw operation at 981.5 and 1001 nm, fabricated by liquid phase epitaxy and femtosecond laser microstructuring, is reported. A planar waveguide was fabricated by growing an Yb3+-doped KY1-x-yGdxLuy(WO4)2 epitaxial layer by liquid phase epitaxy over a KY(WO4)2 substrate. This planar waveguide was then microstructured by means of a multiplexed beam femtosecond laser writing technique in order to define ridge waveguides. Mirrorless laser action is demonstrated in ridge waveguides with different fabrication parameters, obtaining maximum slope efficiency of 78% versus absorbed power, which confirms the feasibility of this technique for the development of integrated laser devices.
