Abstract

We measured for the first time the influence of the Gouy effect on focused few-cycle laser pulses. The carrier-envelope phase is shown to undergo a smooth variation over a few Rayleigh distances. This result is of critical importance for any application of ultrashort laser pulses, including high-harmonic and attosecond pulse generation, as well as phase-dependent effects.

摘要

我们首次测量了古依效应（Gouy effect）对聚焦的少周期激光脉冲的影响。结果表明，在几个瑞利距离内，载波包络相位会经历平滑变化。这一结果对于超短激光脉冲的任何应用都至关重要，包括高次谐波和阿秒脉冲的产生，以及相位相关效应。
