我们首次证明电子存储环上的种子谐波产生可以在真空紫外光谱范围内产生相干光脉冲。该实验在 Elettra 上进行，产生 132 nm 的相干脉冲，持续时间约为 100 fs。光源重复率为1kHz，偏振可调；它非常明亮，峰值功率比自发同步加速器辐射高几个数量级。由于稳定性高，该源用于测试光电子显微镜实验。我们预计存储环上的种子谐波产生可以导致时间分辨飞秒光谱和显微镜的前所未有的发展。
We demonstrate for the first time that seeded harmonic generation on electron storage rings can produce coherent optical pulses in the vacuum ultraviolet spectral range. The experiment is performed at Elettra, where coherent pulses are generated at 132 nm, with a duration of about 100 fs. The light source has a repetition rate of 1 kHz and adjustable polarization; it is very bright, with a peak power several orders of magnitude above that of spontaneous synchrotron radiation. Owing to high stability, the source is used in a test photoemission electron microscopy experiment. We anticipate that seeded harmonic generation on storage rings can lead to unprecedented developments in time-resolved femtosecond spectroscopy and microscopy.
