在正常色散范围内的高能激波阵面辅助共振辐射

High-energy, shock-front assisted resonant radiation in the normal dispersion regime

Thomas Roger, Mohammed F. Saleh, Samudra Roy, Fabio Biancalana, Chunyong Li, Daniele Faccio

摘要:

我们提出了一个简单而有效的理论,预测共振辐射带的存在,在介质的深层正常群速度色散区,即使在没有零群速度色散点。当介质被高能超短脉冲泵浦时,这种辐射是明显的,并且它是由NLSE中的克尔项和激波项之间的相互作用驱动的。在体硅中进行的精确实验完全支持我们的理论发现的理论相位匹配条件。

英文摘要:

We present a simple yet effective theory that predicts the existence of resonant radiation bands in the deep normal group velocity dispersion region of a medium, even in absence of a zero-group velocity dispersion point. This radiation is evident when the medium is pumped with high-energy ultrashort pulses, and it is driven by the interplay between the Kerr and the shock terms in the NLSE. Accurate experiments performed in bulk silica fully support the theoretical phase-matching condition found by our theory.
