A high power diode-pumped Q-switched intracavity-doubled Nd:YAG laser has been developed successfully.A Q-switched laser output of 32.5W with 350W pumping power is obtained at 7kHz using a 30% output coupler.A green output of 32.5W is achieved with pulse duration of about 120ns using a type II KTP crystal.The output beam exhibits a smooth Gaussian-like profile in the far field and the beam quality factor is measured to be 3.6.
