With the emergence of high-repetition-rate few-cycle laser pulse amplifiers aimed at investigating ultrafast dynamics in atomic, molecular, and solid-state science, the need for ever faster carrier-envelope phase (CEP) detection and control has arisen. Here we demonstrate a high-speed, continuous, every-single-shot measurement and fast feedback scheme based on a stereo above-threshold ionization time-of-flight spectrometer capable of detecting the CEP and pulse duration at a repetition rate of up to 400 kHz. This scheme is applied to a 100 kHz optical parametric chirped pulse amplification few-cycle laser system, demonstrating improved CEP stabilization and allowing for CEP tagging.
随着旨在研究原子、分子和固态科学超快动力学的高重复率少周期激光脉冲放大器的出现，对更快的载波包络相位（CEP）检测和控制的需求已经出现。在这里，我们展示了一种基于立体过阈值电离飞行时间光谱仪的高速、连续、单次测量和快速反馈方案，该方案能够以高达 400 kHz 的重复率检测 CEP 和脉冲持续时间。该方案应用于 100 kHz 的光参变啁啾脉冲放大少周期激光系统，证明了 CEP 稳定的改进，并允许 CEP 标记。
