Dajun IssueVolume: 2025-05-06 Abstract: Generating Bessel-Gauss beams in the extreme ultraviolet (EUV) with attosecond pulse durations poses a significant challenge due to the limitations of conventional transmission optical components. Here, we propose a novel approach to produce such beams by inducing an annular EUV source through high-order harmonic generation (HHG) under nonadiabatic phase-matching conditions. The resulting light pulse maintains temporal coherence and manifests attosecond pulse trains as confirmed by the reconstruction of attosecond beating by interference of two-photon transitions (RABBIT) measurements. Macroscopic HHG calculations reproduce the measured spatiotemporal structures, Pan, 宏观HHG计算再现了测量的时空结构, Ma, Wang,这一点通过双光子跃迁干涉(RABBIT)测量重建阿秒拍频得到了证实, Sizuo,传播模拟进一步证实了这种方法产生阿秒贝塞尔-高斯光束的可行性, Huiyong,。
