摘要： 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$\mu$m and optical to optical conversion efficiency of 39.0{\%} are obtained at the pump power of 9.0W.
