我们已经证明了直接产生4.6-nJ 78.9-fs的超短脉冲,峰值功率为58千瓦的全光纤净正常色散振荡器。这样的高峰功率是全光纤振荡器中的记录,并且与啁啾脉冲放大系统相当。相应的谱具有陡峭的谱边,这是耗散孤子(DS)的典型形状。同时,通过调节偏振控制器,可以实现光谱宽度在40 ~ 58 nm范围内的可调,通过增加泵浦功率,可以实现脉宽在1.7 ps ~ 120 fs范围内的可调,具有较好的应用前景。此外,我们还首次从实验上证明了直扩激光器的谱宽与泵浦功率的关系。
We have demonstrated the direct generation of 4.6-nJ 78.9-fs ultrashort pulses with 58 kW peak power in an all-fiber net-normal-dispersion oscillator. Such high peak power is a record in an all-fiber oscillator and is comparable to chirped-pulse amplification systems. The corresponding spectrum has steep spectral edges, which is the typical shape of dissipative solitons (DS). Also, we find that the spectral width is tunable from 40 to 58 nm by adjusting polarization controllers, and the pulse duration can be tuned from 1.7 ps to 120 fs through increasing the pump power, which is attractive to applications. Besides, we demonstrate experimentally the relationship between spectral width and the pump power of DS laser for the first time.
