Efficient cw self-frequency-doubled green laser output of 160 mW has been obtained from Yb:YAl<sub>3</sub>(BO<sub>3</sub>)<sub>4</sub> crystal pumped by 1.4-W incident power from a fiber-coupled 976-nm laser diode. The incident-pump-power–green-output-power conversion efficiency is greater than 11.3%, and the electrical-input–green conversion efficiency is 3.9%. Tunable green output from 513.0 to 545.8 nm is also demonstrated with a quartz birefringent filter.
