We present a solid-state laser system that generates 750 mW of continuous-wave, single frequency, output at 313 nm. Sum-frequency generation with fiber lasers at 1550 nm and 1051 nm produces up to 2 W at 626 nm. This visible light is then converted to UV by cavity-enhanced second-harmonic generation. The laser output can be tuned over a 495 GHz range, which includes the 9Be+ laser cooling and repumping transitions. This is the first report of a narrow linewidth laser system with sufficient power to perform fault-tolerant quantum-gate operations with trapped 9Be+ ions using stimulated Raman transitions.
