Abstract
A 555 nm all solid-state continuous-wave yellow-green laser with 946 nm wavelength from 4F3/2-4I9/2 transition in Nd∶YAG and 1 342 nm wavelength from 4F3/2-4I13/2 transition in Nd∶YVO4 is reported.555 nm yellow-green laser is obtained using a doubly folded-cavity and type-I critical phase matching LBO crystal intracavity sum frequency mixing by 946 nm and 1 342 nm.When the incident pumped powers of Nd∶YAG and Nd∶YVO4 crystals are 12 W and 8 W,respectively,the output power of 555 nm yellow-green laser in TEM00 mode is 542 mW,also its power stability in 4 h is better than ±3.7%.The experimental results show that the intracavity sum-frequency mixing is an effective method for 555 nm laser and it can be applied to other two laser crystals to obtain more all-solid-state lasers with different wavelengths.
