Abstract A maximum of 5.5 W of cw TEM₀₀ mode output at 532nm has been obtained by intracavity frequency doubling with a KTP crystal in an Nd: YVO₄ laser doubly-pumped with 20 W diode pumping power. The optical-optical conversion efficiency is 27.5%. The influence of thermal lensing at high pumping power in the end-pumped Nd:YVO₄ laser is discussed. The Nd:YVO₄ laser has a good power stability of 1.6%.
