ABSTRACT
We report on the first, to the best of our knowledge, Kerr-lens mode-locked laser based on an Yb3+-doped perovskite-type orthoaluminate crystal exploiting two different principal light polarizations. The Yb(Y,Gd)AlO3 laser delivers soliton pulses as short as 32 fs at 1067â
nm with an average output power of 328â
mW and a pulse repetition rate of â¼84.6â
MHz for E || a polarization. For the orthogonal E || b polarization, 33-fs pulses are generated at 1057â
nm with an average output power of 305â
mW. Power scaling to a maximum average output power reaching 2.07 W is achieved at the expense of longer pulse duration (72 fs for E || b), corresponding to an optical efficiency of 43.9% and a peak power of 303â
kW.
