Attosecond timing with spectral resolution- What comes next?
The observation of ultrafast electron motion in atomic or molecular systems is a fundamental aspect in physics and is enabled by the generation of attosecond pulses in the XUV spectral range.
A key advantage of attosecond pulse trains over isolated attosecond pulses is their high spectral resolution still retaining high temporal resolution [1]. I will introduce attosecond measurements using attosecond pulse trains near resonances. I will height the role of continuum-continuum transitions in attosecond time delay measurements within a perturbative approach [3].
In the future, these experiments will benefit from high-repetition rate attosecond experiments based on optical parametric amplifier system [2].
