    In KY(WO4)2:Gd3+,Lu3+,Yb3+ channel waveguides, we produced 418 mW of output power at 1023 nm with 71% slope efficiency versus launched pump power. Grating tuning in an extended cavity provided laser operation from 981 nm to 1045 nm. When pumping at 973 nm, lasing at 981 nm with a record-low quantum defect of 0.8% was achieved.
