Discretely selectable multiwavelength operation of a semiconductor saturable absorber mirror mode-locked Nd:YVO₄...

We report on a semiconductor saturable absorber mirror mode-locked Nd:YVO₄ laser operating at discretely selectable 1064.0, 1073.0, 1085.1 nm wavelengths with the average output powers of more than 2.2 W at each of the three wavelengths. The optical-to-optical efficiencies and the slope efficiencies were larger than 19% and 29% for each of the three wavelengths, and the pulse durations at the highest output powers were 13.1, 10.3, and 8.4 ps, respectively.
