Title: Pulse analysis by delayed absorption from a coherently excited atom

Abstract

In this tutorial, we provide a short review of attosecond pulse characterization techniques and a pedagogical account of a recently proposed method called Pulse Analysis by Delayed Absorption (PANDA) [S. Pabst and J. M. Dahlstr¨om, Phys. Rev. A 94, 013411 (2016)]. We discuss possible implementations of PANDA in alkali atoms using either principal quantum number wave packets or spin-orbit wave packets. The main merit of the PANDA method is that it can be used as a pulse characterization method that is free from atomic latency effects, such as scattering phase shifts and long-lived atomic resonances. Finally, we propose that combining the PANDA method with angle-resolved photoelectron detection should allow for experimental measurements of attosecond delays in photoionization from bound wave packets on the order of tens of attoseconds.

Attosecond transient absorption of a bound wave packet coupled to a smooth continuum

Journal Article Dahlström, Jan Marcus ; Pabst, Stefan ; Lindroth, Eva - Journal of Optics

Here, we investigate the possibility of using transient absorption of a coherent bound electron wave packet in hydrogen as an attosecond pulse characterization technique. In a recent work, we have shown that photoionization of such a coherent bound electron wave packet opens up for pulse characterization with unprecedented temporal accuracy—independent of the atomic structure—with maximal photoemission at all kinetic energies given a wave packet with zero relative phase. Here, we perform numerical propagation of the time-dependent Schrödinger equation and analytical calculations based on perturbation theory to show that the energy-resolved maximal absorption of photons from the attosecond pulse does not uniquely occur at a zero relative phase of the initial wave packet. Instead, maximal absorption occurs at different relative wave packet phases, distributed as a non-monotonous function with a smoothmore »« less

Reconstruction of the complex angle-dependent photoionization transition dipole from a laser-dressed streaking experiment

Journal Article Zhao, Xi ; Wei, Hui ; Yu, Wei-Wei ; ... - Physical Review A

We study the retrieval of the angular dependence of the photoionization transition dipole phase of an attosecond XUV pulse in order to reconstruct the whole photoelectron wave packet after the photoemission process. Using a one-electron model Ar atom, we show that the full electron wave packet can be reconstructed from IR-free photoelectron angular distributions and the streaking electron spectra in an IR-dressed XUV photoionization, with photoelectrons along the common polarization direction of the two pulses. The method relies on the validity of the strong-field approximation so it is valid only for higher energy photoelectrons. Here, we also point out thatmore »« less

Two-Center Interference in the Photoionization Delays of Kr 2

Journal Article Heck, Saijoscha ; Han, Meng ; Jelovina, Denis ; ... - Physical Review Letters

Herein we present the experimental observation of two-center interference in the ionization time delays of Kr₂. Using attosecond electron-ion-coincidence spectroscopy, we simultaneously measure the photoionization delays of krypton monomer and dimer. The relative time delay is found to oscillate as a function of the electron kinetic energy, an effect that is traced back to constructive and destructive interference of the photoelectron wave packets that are emitted or scattered from the two atomic centers. Our interpretation of the experimental results is supported by solving the time-independent Schrödinger equation of a 1D double-well potential, as well as coupled-channel multiconfigurational quantum-scattering calculations ofmore »« less

Frequency-resolved optical gating for complete reconstruction of attosecond bursts

Journal Article Mairesse, Y ; Quere, F - Physical Review. A

We describe a method for the complete temporal characterization of attosecond extreme ultraviolet (xuv) fields. An electron wave packet is generated in the continuum by photoionizing atoms with the attosecond field, and a low-frequency dressing laser pulse is used as a phase gate for frequency-resolved-optical-gating-like measurements on this wave packet. This method is valid for xuv fields of an arbitrary temporal structure, e.g., trains of nonidentical attosecond pulses. It establishes a direct connection between the main attosecond characterization techniques demonstrated experimentally so far, and considerably extends their scope, thus providing a general perspective on attosecond metrology.

Attosecond photoionization of coherently coupled electronic states

Journal Article Yudin, G L ; National Research Council of Canada, Ottawa, Ontario, K1A 0R6 ; Chelkowski, S ; ... - Physical Review. A

We study analytically the photoionization of a coherent superposition of atomic and molecular electronic states by an ultrashort, attosecond x-ray pulse. We show that the broad photoelectron spectrum contains detailed information about the time-dependent electron wave packet. The asymmetry of the photoelectron momentum distribution measures the momentum asymmetry of the initial bound-state wave packet. We show that molecular interference modulates the time-dependent photoelectron spectrum and asymmetry. The modulation also depends on the internuclear separation. The photoelectron spectrum and its asymmetry monitors coherent electron motion and in principle electron transfer on the attosecond time scale.
