Dual-wavelength CW a-cut Nd:YVO4 laser at 1064.3 and 1066.7 nm

Abstract We demonstrate a dual-wavelength continuous-wave (CW) Nd:YVO4 laser working at 1064.3 and 1066.7 nm. At a pump power of 7.25 W, the maximum total output power is 1140 mW and the optical conversion efficiency is 15.7%. The spectral line-widths of the dual-wavelength line are 1.1 nm and 1.2 nm, respectively. This laser system is very simple, compact and efficient.
