Abstract
We present for the first time a dual-wavelength laser operation at 1064 and 914 nm in two NdYVO4 crystals. A 879 nm laser diode is used to pump the first Nd:YVO4 crystal emitting at 914 nm, and the second Nd:YVO4 laser emitting at 1064 nm intracavity pumped at 914 nm. A total output power of 4.28 W at the two fundamental wavelengths was achieved at the absorbed pump power of 13.8 W. The M2 values for 914 and 1064 nm lights at the maximum output power were found to be around 1.3 and 1.1, respectively.
