In order to obtain 589nm yellow laser with high beam quality and high stability,double acousto-optic Q-switches and T-shaped composite cavity were adopted.Diode-side-pumped Nd:YAG and KTP intracavity sum-frequency converter with Ⅱ-type critical phase-matching were used.On the basis of theoretical analysis and experimental verification,the maximum power of 589nm laser reached 3.8W with pulse width of 135ns when the total pumping current was 36A and the repetition frequency was 10kHz.The result showed that high beam quality and high stable 589nm laser could be obtained by means of T-shaped composite cavity.This result is quite helpful for the realization of yellow laser application in the medical field.
