摘要：

A sum-frequency yellow-green laser at 554.9 nm is reported by this paper, 946 nm wavelength is obtained from F-4(3/2)-I-4(9/2) transition in Nd:YAG and 1342 nm wavelength is obtained from F-4(3/2)-I-4(13/2) transition in Nd:YVO4. Using a doubly folded-cavity type-II critical phase matching KTP crystal intra cavity to make 946 nm laser from Nd:YAG and 1342 nm laser from Nd:YVO4 frequency summed, with incident pumped power of 30W in Nd:YAG and 20W in Nd:YVO4, TEM00 mode yellow-green laser at 554.9 nm at 1.15W is obtained and its M-2 factor is less than 1.22. The experimental results show that the Nd:YAG and Nd:YVO4 crystals intra-cavity sum-frequency mixing is an effective method for yellow-green laser and it can be applied to other two laser crystals to obtain more all-solid-state lasers with different wavelengths.
