Attosecond science – Nobel Prize session

Invited Oral Presentation

Free-electron lasers are the brightest sources of attosecond x-ray pulses, improving the brightness by more than six orders of magnitude with respect to table-top high-harmonic sources. This huge increase in brightness has opened new avenues for attosecond science, leading to the demonstration of non-linear x-ray spectroscopy and x-ray pump/probe experiments with attosecond resolution....

228. Attosecond Science at FELs (FRBI02)

Attosecond science – Nobel Prize session

Invited Oral Presentation

The development of trains and isolated attosecond pulses in the extreme ultraviolet (XUV) and soft X-ray range at free-electron lasers (FELs) has opened up new avenues for attosecond science [1,2]. These pulses possess notable characteristics such as energy tunability, high peak intensities and, in the case of seeded FELs, precise phase and amplitude control.
In this presentation, I will show...

231. A novel single-shot characterization method for attosecond FEL pulses using self-referenced spectral interferometry (FRBI03)

Attosecond science – Nobel Prize session

Invited Oral Presentation

The complete spectrotemporal characterization of attosecond X-ray free-electron lasers (FELs) is of great importance for the ultrafast scientific experiments. Currently, the lack of high-precision characterization methods has become a key bottleneck that limits the application of attosecond X-ray FELs to some extent. To address this issue, we proposed a novel method, demonstrated by a...

276. Applications of Attosecond Soft-X-ray pulses to Photoemission Chronoscopy and Transient Absorption (FRBI04)

Hans Jakob Woerner (ETH Zurich)

Attosecond science – Nobel Prize session

Invited Oral Presentation

Attosecond soft-X-ray pulses can nowadays be produced either through high-harmonic generation (HHG) or free electron lasers (FELs). Whereas HHG sources achieve the shortest durations (43 as [1]), FELs achieve the highest peak intensities [2]. I will discuss recent experiments that exploit the complementarity of these attosecond sources. Combining attosecond soft-X-ray pulses from LCLS with...
