Continuous-wave and mode-locked lasers on the base of partially disordered crystalline Yb3+:{YGd2}[Sc2](Al2Ga)O12 ceramics.

We present cw and mode-locked laser operations on the base of partially disordered crystalline Yb(3+):{YGd(2)}[Sc(2)](Al(2)Ga)O(12) ceramics. In continuous-wave laser operations, the average power of 2.9 W at the wavelength of 1051 nm and 2.8 W at the wavelength of 1031 nm with above 40% optical-to-optical efficiencies were achieved. In mode-locked laser operation, pulses as short as 69 fs with the average power of 820 mW was also obtained.
