Continuous wave 543 nm laser emission at powers as high as 105 mW is achieved by using an LD with a power of 2 W to pump 0.8% (atom percent) Nd:YVO4 crystal, with intracavity frequency doubling in a 10 mm long type I critical phase matching LBO crystal and a simple linear resonator. The optical to optical conversion efficiency is up to 5.53% with the incident pump power of 1.9 W, and the long term stability of the output power is better than 3% in 3 h.
