A dual-pump 10 GHz mode-locking erbium-doped fiber laser was demonstrated. With 10-GHz signal modulation of the modulator, less than 12 ps mode-locked pulse at 10 GHz repetition rate with 1.097 mW average output power was obtained. The corresponding spectrum width is 0.277 nm, which is centered at 1561 nm. The corresponding product of time and bandwidth is Δ<i>v</i>*Δ<i>t</i> which equals 0.433. Gaussian pulse shape is assumed, the output pulse is almost transform limited. Compared with single-pump fiber ring laser, the dual-pump fiber ring laser is helpful for suppression of supermode noise, which make this kind of fiber ring laser more stable.
We report on generation of fundamental soliton using a section of photonic crystal fibers (PCFs) with high nonlinearity
and anomalous dispersion. 10 GHz output pulses with 6.108 mW average power and duration of less than 10 ps have been
generated from an actively mode-locking fiber ring laser based on PCFs. The spectral of output pulses can be tunable from 1532 nm to
1565 nm. According to the estimated peak power of 6.108×10<sup>-2</sup> W for 10 ps pulse, 1.026 order soliton occurred.
