Amplitude and phase spectroscopy of attosecond electron wave packets
نویسندگان
چکیده
Synopsis: The interference of attosecond electron wavepackets, created by high harmonic and femtosecond laser pulses, is measured. The first electron wavepacket is generated by direct ionization of He, and the second one by the two step process of resonant excitation by the attosecond high harmonic pulse and subsequent ionization by the laser pulse. The amplitude and phase retrieved from the interferogram show the ionization dynamics of He.

Attosecond dynamics through a Fano resonance: Monitoring the birth of a photoelectron.
The dynamics of quantum systems are encoded in the amplitude and phase of wave packets. However, the rapidity of electron dynamics on the attosecond scale has precluded the complete characterization of electron wave packets in the time domain. Using spectrally resolved electron interferometry, we were able to measure the amplitude and phase of a photoelectron wave packet created through a Fano ...
متن کاملAttosecond electron wave-packet interference observed by transient absorption.
We perform attosecond time-resolved transient absorption spectroscopy around the first ionization threshold of helium and observe rapid oscillations of the absorption of the individual harmonics as a function of time delay with respect to a superimposed, moderately strong infrared laser field. The phase relation between the absorption modulation of individual harmonics gives direct evidence for...
متن کاملProbing electronic dynamics during photochemical reactions.
This review discusses a new method for probing the evolution of the valence-electron structure of molecules during chemical reactions. The method relies on the interaction of an intense infrared laser pulse with molecules that results in the emission of attosecond pulses (1 as = 10(-18) s) in a process known as high-harmonic generation. Time-resolved high-harmonic spectroscopy measures the phas...

High-harmonic spectroscopy utilizes attosecond techniques to measure single-atom or molecule photorecombination cross sections [1–4]. While the amplitude of the extreme ultraviolet (XUV) light can be easily measured, the phase is much more challenging to access, yet it contains information about the attosecond synchronization of electron recollision dynamics [5], the instantaneous ionization po...
متن کاملThe robustness of attosecond streaking measurements.
We investigate attosecond streaking measurements, where a spectrogram is described by an ensemble of electron wave packets. Such a description may be required for processes more complex than direct photoemission from an isolated atom; an ensemble of wave packets may also be needed to describe the role of shot-to-shot fluctuations or a non-uniform spatio-temporal profile of attosecond light puls...
