We report multiwatt, diode-pumped cw operation on the 4F3/2–4I9/2 laser transition at 914.5 nm in Nd:YVO4, for which an output power of 3.0 W and a slope of efficiency of 22.8% were achieved. For the corresponding laser transition of Nd:YAG at 946 nm an output power of 5.35 W and a slope efficiency of 40.2% were measured. By intracavity frequency doubling, an output power of 1.5 W at 473 nm was generated.
