Means of intra-cavity frequency doubling 914 nm transition of Nd:YVO4 pumped by laser diode (LD) is an important technical scheme to get high power blue laser output, thus achieving high efficiency 914 nm laser is the key point. A high power continuous-wave (CW) end-pumped Nd:YVO4 laser operating at 914 nm by utilizing a quasi-three-level transition was demonstrated. A 0.1% Nd-doped bulk Nd:YVO4 was applied to reduce the thermal effect in the laser crystal. In order to avoid re-absorption losses further, a suitable length of the crystal was chosen based on a careful calculation. Two wavelengths of 1064 nm and 1342 nm with high gain were restrained effectively by suitable control of the parameters of the medium film on cavity mirrors. Finally, the laser was operated at a very low threshold at the pumping power of 8.5 W, and a 914 nm laser with power of 7.2 W was gotten at the pumping power of 31 W. The slope efficiency of the laser was 32%, and the optical-to-optical efficiency was 23.2%.
