The recent development of ultrafast extreme ultraviolet (XUV) coherent light sources bears great potential for a better understanding of the structure and dynamics of matter. Promising routes are advanced coherent control and nonlinear spectroscopy schemes in the XUV energy range, yielding unprecedented spatial and temporal resolution. However, their implementation has been hampered by the experimental challenge of generating XUV pulse sequences with precisely controlled timing and phase properties. In particular, direct control and manipulation of the phase of individual pulses within an XUV pulse sequence opens exciting possibilities for coherent control and multidimensional spectroscopy, but has not been accomplished. Here, we overcome these constraints in a highly time-stabilized and phase-modulated XUV-pump, XUV-probe experiment, which directly probes the evolution and dephasing of an inner subshell electronic coherence. This approach, avoiding any XUV optics for direct pulse manipulation, opens up extensive applications of advanced nonlinear optics and spectroscopy at XUV wavelengths.

使用相位操纵的极紫外脉冲跟踪亚秒电子相干性。
超快极紫外（XUV）相干光源的最新发展为更好地了解物质的结构和动力学具有巨大的潜力。有希望的路线是XUV能量范围内的先进相干控制和非线性光谱方案，可产生空前的时空分辨率。然而，它们的实现受到了产生具有精确控制的时序和相位特性的XUV脉冲序列的实验挑战的阻碍。特别地，在XUV脉冲序列内直接控制和控制单个脉冲的相位为相干控制和多维光谱学提供了令人兴奋的可能性，但尚未实现。在这里，我们通过高度时间稳定和相位调制的XUV泵，XUV探针实验克服了这些限制，它直接探讨了内部子壳电子相干性的演变和相移。这种方法避免了任何用于直接脉冲操纵的XUV光学器件，从而开创了在XUV波长下先进的非线性光学器件和光谱学的广泛应用。
