Efficient cw self-frequency-doubled green laser output of 160 mW has been o
btained from Yb:YAl3(BO3)(4) crystal pumped by 1.4-W incident power from a
fiber-coupled 976-nm laser diode. The incident-pump-power-green-output-powe
r conversion efficiency is greater than 11.3%, and the electrical-input-gre
en conversion efficiency is 3.9%. Tunable green output from 513.0 to 545.8
nm is also demonstrated with a quartz birefringent filter. (C) 2000 Optical
