摘要

We demonstrate the dissipative soliton mode locking in a diode pumped Yb∶GdYSiO5(Yb∶GYSO) laser operating in the positive dispersion regime.We obtain stable passively mode-locked pulses with strong positive chirp and with very steep spectral edges.The central wavelength is 1050 nm with bandwidth of about 4 nm,autocorrelation trace shown the typical pulse duration is about 3.5 ps.We obtain the maximum average power of 558 mW for a 3.3-W absorbed pump power,with 22％ slope efficiency,and a 78-MHz pulse repetition frequency.
