Abstract—We report an efficient intracavity second-harmonic generation (SHG) at 1066 nm in a non-linear
optical crystal, GdCa₄O(BO₃)₃ (GdCOB), performed with a diode end pumped continuous-wave (CW)
Nd:LuVO₄ laser. In the case of a laser with a Nd:LuVO₄ crystal frequency-doubled with a GdCOB crystal cut
for type I frequency doubling. A CW SHG output power of 5.18 W has been obtained using a 10 mm long
GCOB crystal. The optical conversion efficiency with respect to the incident pump power was 28.5%.
