| 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 671 nm by intracavity frequency doubling of a Nd∶YVO4 laser based on the nonlinear crystal LBO is achieved.The 671 nm laser reaches 1.203 W when the absorbed pump power is 24.56 W,with TEM00 mode and an optical to optical efficiency of 4.9%.The amplitude noise is 0.52% (rms) in an hour when the output power is at about 1.08 W. |
