Abstract

We report on the optical properties of Yb3+-doped disordered Y3Al5O12/Y3Sc2Al4O12 (Yb:Y3ScAl4O12) ceramic lasers. Efficient cw laser oscillation of over 70% slope efficiency was obtained with over 40 nm tuning range at room temperature. We also achieved pulses as short as 580 fs with 25mW output power and 830 fs pulses with output power of 150 mW.
