在高脉冲能量（>10 nJ）和短脉冲宽度（<100 fs）的极限条件下，研究了Yb光纤飞秒激光器的性能。通过减小非线性偏振旋转的强度并通过腔内频率滤波器引入幅度调制，可以产生具有前所未有的峰值功率的脉冲。该激光器发出稳定的13 nJ脉冲，去啁啾至55 fs持续时间，并能够提供130 kW的峰值功率。
The performance of a femtosecond Yb fiber laser is investigated in the limit of high pulse energy (>10 nJ) and short pulse duration (<100 fs). By reducing the strength of nonlinear polarization rotation and introducing amplitude modulation through an intracavity frequency filter, pulses with unprecedented peak powers can be generated. The laser emits stable 13 nJ pulses that are dechirped to 55 fs duration and are capable of providing 130 kW peak power.
