短周期脉冲传播

Few cycle pulse propagation

P. Kinsler, G. H. C. New

摘要:

我们提出了一个全面的框架,用于治疗的非线性相互作用的几个周期的脉冲使用的包络描述,超越了传统的SVEA方法。这是适用于一系列的模拟,演示了如何影响的$χ^{(2)}$非线性之间的许多周期和几个周期的情况下不同。我们的方法,包括衍射,色散,多个字段,和广泛的非线性,建立在Brabec和Krausz[1]和Porras[2]的工作。直到最后阶段考虑特定问题时才进行近似。这篇arXiv论文的原始版本(v1)接近已发表的Phys.Rev.A。版本,尺寸小得多。

英文摘要:

We present a comprehensive framework for treating the nonlinear interaction of few-cycle pulses using an envelope description that goes beyond the traditional SVEA method. This is applied to a range of simulations that demonstrate how the effect of a $χ^{(2)}$ nonlinearity differs between the many-cycle and few-cycle cases. Our approach, which includes diffraction, dispersion, multiple fields, and a wide range of nonlinearities, builds upon the work of Brabec and Krausz[1] and Porras[2]. No approximations are made until the final stage when a particular problem is considered. The original version (v1) of this arXiv paper is close to the published Phys.Rev.A. version, and much smaller in size.
