Abstract
We demonstrate supercontinuum spectral phase interferometry with an isolated attosecond pulse (IAP). The interferogram indicates a high degree of temporal coherence over the full IAP continuous spectrum, which will contribute to exploring dispersive electron dynamics. 1. Introduction Combining spatial and temporal detection by means of self-referencing interferometry with high-order harmonics has a variety of applications in, for instance, molecular orbital tomography [1], nanoscale sample imaging [2], and the characterization of complex electron dynamics [3]. Meanwhile, an isolated attosecond pulse (IAP) with short duration and broadband supercontinuum spectrum have contributed to observing ultrafast electronic motions in various targets [4]. The self-referencing interferometry with two IAPs will be an important tool for observing electron dynamics through the phase-based spectroscopy. Here, we demonstrated the supercontinuum spectral phase interferometry with IAP [5]. The coherence over broadband spectral region will contribute to studying the dispersive electron dynamics through Fourier spectroscopy.
