Continuous-wave dual-wavelength operation of a diode-end-pumped Nd:LuVO₄ laser

A dual-wavelength continuous-wave (CW) diode-pumped Nd:LuVO4 laser that generates simultaneous laser action at the wavelengths 1066 and 1343 nm is demonstrated. A total dual-wavelength output power of 2.58 W was achieved at the incident pump power of 18.2 W. Furthermore, intracavity sum-frequency mixing at 1066 and 1343 nm was then realized in a LBO crystal to reach the yellow range. We obtained a total CW yellow output power of 830 mW at 594 nm.
