By using the Faraday effect in Nd:YAG and the rotation of polarization in a non plannar ring resonator, single frequency output from an all solid state out of plane Nd:YAG ring laser is demonstrated. The maximum single frequency output of 365 mW at 1064 nm has been achieved with slope efficiency of 36.2%, the intensity fluctuation is less than 2% and the frequency shift is less than 45 MHz in 1 minute. Single frequency output of 75 mW at 532 nm has been obtained by intracavity frequency doubling. The intensity fluctuation for 532 nm is less than 4%.
