Abstract
We report efficient generation of cw yellow light by use of single-pass sum-frequency mixing from a diode-pumped Nd:YVO 4 dual-wavelength laser with periodically poled lithium niobate. A diode-pumped Nd:YVO 4 dual-wavelength laser is implemented with a three-mirror cavity, and the optimum oscillation condition is obtained from theoretical analysis. We extracted 78 mW of power at 593 nm from 1.2 W at 1064 nm and from 1.0 W at 1342 nm in a beam with excellent quality. The output power could probably be increased to ∼92 mW by antireflection coating of the crystal. © 2002 Optical Society of America.
