Abstract

A laser resonator that can compensate the thermal lensing effect of the laser crystal greatly is designed. Thus a continuous wave laser with high stability at 532 nm by intracavity frequency doubling of a Nd: YVO4 laser based on the nonlinear crystal KTP is achieved. The 532 nm laser reaches 5. 3 W when the absorbed pump power is 24. 56 W, with TEM00 mode and an optical to optical efficiency of 21. 6%. The amplitude noise is better than 0. 6% (rms) in an hour when the output power is at about 5W.
