ABSTRACT
We report on the first sub-60 fs pulse generated from a diode-pumped SESAM mode-locked Yb-laser based on a non-centrosymmetric YbYAl3(BO3)4 crystal as a gain medium. In the continuous-wave regime, pumping with a spatially single-mode, fiber-coupled 976â
nm InGaAs laser diode, the YbYAl3(BO3)4 laser generated 391â
mW at 1041.7â
nm with a slope efficiency as high as 65.1%, and a wavelength tuning across 59â
nm (1019 to 1078â
nm) was achieved. By implementing a commercial SESAM to initiate and sustain the soliton type mode-locking, and using only a 1â
mm-thick laser crystal, the YbYAl3(BO3)4 laser delivered pulses as short as 56 fs at a central wavelength of 1044.6â
nm with an average output power of 76â
mW at a pulse repetition rate of â¼67.55â
MHz. To the best of our knowledge, this result represents the shortest pulses ever achieved from YbYAB crystal.
