AI 中文摘要
我们对Mamyshev振荡器与光纤激光器中通过非线性偏振旋转（NPR）实现的锁模所产生的类噪声脉冲（NLP）发射进行了深入对比，在正常和反常色散区域内分析了NLP的时域与频域特性；通过改变输出耦合系数优化输出脉冲能量，结果表明基于NPR的锁模光纤激光器的脉冲能量系统性高于Mamyshev振荡器，原因在于Mamyshev振荡器中的滤波效应会拒绝能量不足以成功通过两个偏移光滤波器的超短脉冲。
英文摘要
We perform an in-depth comparison of noise-like pulse emission from Mamyshev oscillator and mode-locking through nonlinear polarization rotation (NPR) in fiber lasers. NLP's temporal and spectral characteristics are analyzed in both normal and anomalous dispersion regimes. The output coupling coefficient is modified to optimize the energy of the output pulses. It is demonstrated that the pulse energy is systematically higher in NPR-based mode-locking fiber lasers than in Mamyshev oscillators. This is due to the filtering effect in the Mamyshev oscillator which rejects ultrashort pulses whose energy is insufficient to successfully pass through the two shifted optical filters.
