    A double tungstate waveguide with high refractive index contract between layer and substrate is grown and microstructured by Ar beam milling. Channel waveguide lasing with excellent mode confinement, a threshold of 5 mW and slope efficiency of 62% versus launched pump power, and 75 mW output power is demonstrated.
