Continuous-Wave Output of 5.5 W at 532 nm by Intracavity Frequency Doubling of an Nd:YVO4 Laser
-
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%.
