1.34μm Nd:YVO₄ high efficiency laser end-pumped by diode-laser of flat-concave cavity type

The parameters of 1.34\mu m Nd:YVO_4 laser end-pumped with flat-concave cavity are theoretically analysed. The analysis in this paper may be helpful to the designing of kindred lasers. The operation of 1.34\mu m Nd:YVO_4 laser end-pumped by a diode-laser with flat-concave cavity is achieved. The output power of 3.51W at 1.34\mum and optical to optical conversion efficiency of 39.0\% are obtained at the pump power of 9.0W.
