We report multiwatt, diode-pumped cw operation on the <sup>4</sup><i>F</i><sub>3/2</sub>–<sup>4</sup><i>I</i><sub>9/2</sub> laser transition at 914.5 nm in Nd:YVO<sub>4</sub>, 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.
