title: 2.8 W end-pumped Yb3+:LiYF4 waveguide laser.
abstract: Continuous wave, room temperature laser oscillation around 1 μm is reported for the first time (to our knowledge) from an Yb(3+)-doped fluoride crystalline waveguide fabricated by using the liquid phase epitaxy technique. Maximum slope efficiencies of 76% and 41% were obtained for laser emissions at 994 and 1020 nm, respectively. A maximum output power of 2.8 W was obtained at 1020 nm by pumping around 980 nm with a high-brightness fiber laser in an 87 mm long V-shaped cavity.
