Poor man&#x2019;s channel waveguide laser: KY(WO<inf>4</inf>)<inf>2</inf>:Yb

Abstract

Using low-cost fabrication methods, liquid phase epitaxy and strip-loading a short fiber piece with a fluid, channel waveguide lasing is demonstrated in KY(WO<sub>4</sub>)<sub>2</sub>:Yb<sup>3+</sup>. Threshold is 82 mW, slope efficiency 30%, and output power 14 mW.
