A yellow continuous wave with beam quality M-2 = 4.6 and output power of 4.8 W at 589 nm is generated by intracavity sum-frequency mixing of 1064 nm and 1319 nm radiations of ND:YAG laser. To achieve high beam quality at high power, thermally near-unstable flat-flat resonators with two-rod birefringence compensation are designed to obtain the large fundamental mode size inside the ND:YAG rods and the same beam width inside the KTP crystal. The optimal intracavity power ratio of both 1064 nm and 1319 nm beams is also considered. The output power fluctuation of the yellow laser remains less than 5% in four hours.
