Numerical simulations are used to study the interaction dynamics between pump spectral broadening and third harmonic generation during supercontinuum generation in a highly nonlinear fused silica nanowire using sub-100 fs pump pulses. In particular, we show that the superposition of the generated third harmonic with the spectrally-broadened pump pulse exhibits significant dependence on the input pump carrier envelope phase, and we examine this dependence as a function of pulse duration and propagation distance.
利用数值模拟研究了在高度非线性熔融石英纳米线中使用亚100飞秒泵浦脉冲产生超连续谱时泵浦光谱展宽与三次谐波产生之间的相互作用动力学。特别地，我们表明，产生的三次谐波与光谱展宽的泵浦脉冲的叠加对输入泵浦载波包络相位表现出显著的依赖性，并且我们将这种依赖性作为脉冲持续时间和传播距离的函数进行了研究。
