We report the generation of 6-nJ chirped pulses from a mode-locked Yb fiber laser at 1.03 micrometre. A linear anomalous-dispersion segment suppresses wave-breaking effects of solitonlike pulse shaping at high energies. The dechirped pulse duration is 50 fs, and the energy is 5 nJ. This laser produces twice the pulse energy and average power, and approximately five times the peak power, of the previous best mode-locked fiber laser. It is to our knowledge the first fiber laser that directly offers performance similar to that of solid-state lasers such as Ti:sapphire.
我们报道了从锁模掺镱光纤激光器产生波长为1.03微米、能量为6纳焦的啁啾脉冲。一个线性反常色散段抑制了高能量下类孤子脉冲整形的波破碎效应。啁啾脉冲展宽后的持续时间为50飞秒，能量为5纳焦。该激光器产生的脉冲能量和平均功率是此前性能最佳的锁模光纤激光器的两倍，峰值功率约为其五倍。据我们所知，这是第一台直接提供与诸如钛宝石等固态激光器类似性能的光纤激光器。
