Abstract—We report a yellow-green laser at 544.5 nm generation by intracavity frequency doubling of a con-
tinuous wave (CW) laser operation of a 1089 nm Nd:LuVO₄ laser under in-band diode pumping at 888 nm. An
LBO crystal, cut for critical type I phase matching is used for second harmonic generation of the laser. At an
incident pump power of 17.9 W, as high as 3.81 W of CW output power at 544.5 nm is achieved. The optical-
to-optical conversion efficiency is up to 21.3%, and the fluctuation of the yellow-green output power was better
than 3.7% in the given 4 h.
