    Abstract:
    © 2019 Optical Society of America A surface channel waveguide (WG) laser is produced by diamond saw dicing of a 15 μm thick 10 at. % Tm:KY 1- x- y Gd x Lu y WO 42 monoclinic double tungstate thin film grown by liquid phase epitaxy on an undoped KYWO 42 substrate. The WG propagation losses are 1.1 0.5 dB∕cm. When pumped at 802 nm, laser operation is achieved with a maximum output power of 262 mW at 1833 nm with a record slope efficiency of 82.6% (versus the absorbed pump power) in a TE 10 spatial mode (linear laser polarization, EkN m ). Diamond saw dicing of double tungstate epitaxies is a promising technology for manufacturing WGs for sensing applications.
