Finite-range time delays in numerical attosecond-streaking experiments
We present results of numerical simulations and theoretical classical analysis of time delays with respect to the instant of ionization in a numerical streaking experiment. We show that the time delay is related to a finite range in space, which the emitted electron probes after its transition into the continuum until the streaking pulse ceases. This finite-range time delay results from the cou...
متن کاملAttosecond-streaking time delays: Finite-range property and comparison of classical and quantum approaches
We theoretically study time delays obtained using the attosecond-streaking technique. To this end, we compute time delays by numerically solving the corresponding time-dependent Schrödinger equation and analyze the delays using two classical methods, namely, a perturbative approach and a full numerical solution of Newton’s equation describing the motion of the photoelectron in the continuum. A ...
متن کاملNumerical Simulations of Attosecond Streaking Time Delays in Photoionization
We present results of numerical simulations and theoretical classical analysis of time delays with respect to the instant of ionization in a numerical streaking experiment. These results confirm our previous interpretation of the streaking time delay as a finite-range and fieldweighted time delay. We show that in the streaking experiments the time delay strongly depends on the parameters of the...
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...
متن کاملPhotonic streaking of attosecond pulse trains
High harmonic radiation, produced when intense laser pulses interact with matter, is composed of a train of attosecond pulses. Individual pulses in this train carry information on ultrafast dynamics that vary from one half-optical-cycle to the next. Here, we demonstrate an all-optical photonic streaking measurement that provides direct experimental access to each attosecond pulse by mapping emi...
