The delay and phase dependent behavior of a system for supercontinuum generation by using a microstructured fiber within a synchronously pumped ring resonator is presented numerically. The feedback introduced by the resonator led to an interaction of the supercontinuum with the following femtosecond laser pulses and thus to the formation of a nonlinear oscillator. Via the feedback phase different regimes of nonlinear dynamics, such as steady state, period multiplication, limit cycle and chaos can be adjusted systematically. The spectrum within one regime of nonlinear dynamics can additionally be modified independently from the regime of nonlinear dynamics.
数值呈现了一种利用同步泵浦环形谐振器内的微结构光纤产生超连续谱的系统的延迟和相位相关行为。谐振器引入的反馈导致超连续谱与后续飞秒激光脉冲相互作用，进而形成一个非线性振荡器。通过反馈相位，可以系统地调整非线性动力学的不同状态，如稳态、倍周期、极限环和混沌。在一种非线性动力学状态内的光谱还可以独立于非线性动力学状态进行额外修改。
