电子显微镜和超短脉冲电子束衍射能够以超快时间和原子尺度空间分辨率相结合的方式对瞬态现象进行成像。光学电子束控制的新兴领域允许在光周期水平上操纵相对论性和亚相对论性电子束。具体来说，它能够以阿秒脉冲串和单个阿秒脉冲的形式生成电子束。在这篇综述中，我们描述了阿秒电子束控制的基础知识并概述了最近的实验进展。阿秒亚光周期持续时间的高能电子脉冲为超快化学和物理过程的时空分辨成像、相干光子生成、自由电子量子光学、具有成形波包的电子原子散射和激光驱动粒子加速开辟了新的机会。图形摘要
Electron microscopy and diffraction with ultrashort pulsed electron beams are capable of imaging transient phenomena with the combined ultrafast temporal and atomic-scale spatial resolutions. The emerging field of optical electron beam control allowed the manipulation of relativistic and sub-relativistic electron beams at the level of optical cycles. Specifically, it enabled the generation of electron beams in the form of attosecond pulse trains and individual attosecond pulses. In this review, we describe the basics of the attosecond electron beam control and overview the recent experimental progress. High-energy electron pulses of attosecond sub-optical cycle duration open up novel opportunities for space-time-resolved imaging of ultrafast chemical and physical processes, coherent photon generation, free electron quantum optics, electron–atom scattering with shaped wave packets and laser-driven particle acceleration.Graphical Abstract
