We have investigated the effect of intracavity nonlinear dynamics arising from enhanced peak powers of femtosecond pulses inside broad-bandwidth, dispersion-controlled, high-finesse optical cavities. We find that for chi(3) nonlinearities, when a train of femtosecond pulses are maximally coupled into a cavity by active stabilization of its frequency comb to the corresponding linear resonances of a cavity, enhancement ceases when the peak nonlinear phase shift is sufficient to shift the cavity resonance frequencies by more than a cavity linewidth. In addition, we study and account for the complex spectral dynamics that result from chirping the input pulse and show excellent qualitative agreement with experimental results.
我们研究了宽带、色散控制、高精细度光学腔内飞秒脉冲峰值功率增强所产生的腔内非线性动力学效应。我们发现，对于三阶非线性效应，当通过将频率梳主动稳定到腔的相应线性共振，使一列飞秒脉冲最大程度地耦合到腔内时，当峰值非线性相移足以使腔共振频率偏移超过一个腔线宽时，增强效应就会停止。此外，我们研究并解释了输入脉冲啁啾所导致的复杂光谱动力学，并与实验结果显示出良好的定性一致性。
