    Schematic of a photocathode used for ultrafast electron diffraction[65]. Reprinted from Ref. [65], with the permission of AIP Publishing
    Schematic layout of ultrashort microbunch electron source[75]. Reprinted from Ref. [75], with the permission of AIP Publishing
    Schematic of laser plasma wakefield acceleration[95]. Reprinted from Ref. [95]
    Localized photoemission from a metal tip
    Generation, compression and characterization of subrelativistic electron pulses by light field[9]
    Concept and experimental setup of electron pulses compression by THz[181]
    Concept of electron-beam control by optical field[184]. An electron beam (blue) is modulated by a single field cycle (red) of a phase-controlled waveform when passing through a metallic membrane (green). The temporally modulated electron current is directly characterized by real-space streaking induced by a second single-cycle field (red). Reprinted figure with permission from Ref. [184] Copyright (2020) by the American Physical Society
    Layout of the experimental setup for the generation and detection of attosecond electron pulse trains[185]. The two spatiotemporally separated optical traveling waves-the first for the attosecond electron pulse train generation and the second for its analysis-are generated using two independent Michelson interferometers.

    Direct mapping of attosecond electron dynamics with laser[191]. As an intense laser pulse is reflected on the plasma mirror, it expels electrons at several narrow specific phase windows of the field. These subcycle attosecond electron pulses then experience an integrated momentum kick as they surf the laser electric field (laser streaking) and form the periodic fringes in the far field
