A high-power-output single-frequency Nd: YVO4 infrared laser has been designed and built. The thermal focus length is distinct and sensitivity in case of coherent pumping with high power and is considered in cavity design. A stable ring cavity was important for the laser output frequency tuning. Under single frequency operation, the maximum output power of 3.9w is obtained at 1064nm with the LD pumping power of 16 W. Over 1 GHz continuous frequency tuning was obtained when the cavity length was scanned by PZT. The cavity stability was also analyzed.
