<p>Coherent inverse Compton scattering (CICS) emerges as a promising mechanism for generating high-quality light sources in the X-ray and extreme ultraviolet (EUV) spectral regimes. A key prerequisite for achieving coherence here is the formation of periodically microbunched electron beams. In this work, we investigate the interaction between electron beams and vortex beams, specifically Laguerre-Gaussian (LG) laser beams. Through particle-in-cell (PIC) simulations, we demonstrate that LG laser fields can induce significant modulation of electron densities, resulting in the formation of periodically structured electron microbunches. These microbunches are shown to maintain robustness across a broad interaction region and satisfy the periodic conditions essential for CICS, thereby achieving a coherent enhancement by a factor exceeding 10⁴. This LG-beam-induced novel approach provides a compact, all-optical pathway for generating highly coherent, narrowband radiation in the soft X-ray and EUV regimes, with promising applications in ultrafast science, precision spectroscopy, and nanoscale imaging.</p>
