A compact, high-power, and high-stability Nd:YVO4 laser at 1342 nm has been developed. As high as 11 W cw output for 35 W of incident pump power with a slope efficiency of about 31.4% has been obtained. It has been shown that a reasonable and effective way to improve the output power is to choose a pumping scheme that can effectively extend the range of the stable resonator region by choosing the optimal dopant concentration and length of the laser rod.
