10-GHz straight-cavity SESAM-modelocked Yb:CALGO laser operating in the normal dispersion regime

We demonstrate a 10-GHz SESAM-modelocked Yb:CALGO laser delivering 240 fs at 0.64 W from a straight cavity containing a fanout-apodized-PPLN crystal, which provides soliton modelocking via cascaded second-order nonlinearities and a defocusing-lens effect suppressing Q-switching-damage.
