Growth of Yb:YAB crystal and its laser performance

Single crystal of Yb x Y 1- x Al 3(BO 3) 4 (Yb∶YAB) was grown by using flux method with potassium trimolybdate. 160 mW efficient cw green output was obtained by a fibre coupled 976 nm laser diode pumping. The conversion efficiency is greater than 11 3%, and the pumping conversion efficiency is 3 9%. Tunable green output from 513 0 to 545 8 nm is also demonstrated with a quartz birefringent filter. Enhancing the incident pump power, 1 1 W cw green output is reached.
