High-power 888-nm-pumped Nd:YVO4 1342-nm oscillator operating in the TEM00 mode

We report on a high-power 888-nm-pumped continuous-wave Nd:YVO4 laser at 1342 nm. An output power of 24 W emitted into a diffraction limited beam with an M2 parameter better than <1.1 is demonstrated. At an absorbed pump power of 84 W the optical conversion efficiency is 29%.
