Compression methods for XUV attosecond pulses.
نویسندگان
چکیده
Attosecond extreme-ultraviolet (XUV) pulses generated in gases via high-order harmonic generation typically carry an intrinsic positive chirp. Compression of such pulses has been demonstrated using metallic transmission filters, a method with very limited tunability. We compare here the compression achievable with a diffraction grating based method with that of metallic filters using simulated high harmonic waveforms in the transmission window of metal films.

Characterization of attosecond XUV pulses utilizing a broadband UV ~ VUV pumping
We propose a simple scheme to characterize attosecond extreme ultraviolet (XUV) pulses. A broadband ultraviolet (UV) ∼ vacuum ultraviolet (VUV) pump pulse creates a coherent superposition of atomic bound states, from which photoionization takes place by the time-delayed attosecond XUV probe pulse. Information on the spectral phase of the XUV pulse can be extracted from the phase offset of the i...
متن کاملRealization and characterization of an XUV multilayer coating for attosecond pulses.
The experimental characterization of an aperiodic reflecting multilayer (ML) structure designed to reflect and compress attosecond pulses in the extreme ultraviolet spectral region is presented. The MLs are designed for the 75-105 eV spectral interval with suitable reflectance and phase behavior, in particular high total spectral reflectivity coupled with very wide bandwidth and spectral phase ...
متن کاملMeasurement of attosecond XUV pulses generated with polarization gating by two-dimensional photoelectron spectroscopy
We report on our high speed camera designed for temporal characterization of attosecond pulses (1as =10s) generated with the polarization gating technique. The uniform external magnetic field applied on the timeof-flight spectrometer enlarges the acceptance angle (up to 65 for ~20-eV photoelectrons). By collecting twodimensional momentum images of the photoelectrons, which are ejected by the XU...
متن کاملProduction of Ultrashort FEL XUV Pulses via a Reverse Undulator Taper ?
We adapt the “reverse taper” scheme presented by Saldin et al. (Phys. Rev. ST Accel. Beams, 9, 050702 [2006]) for attosecond pulse production to the XUV/soft-xray regime. We find that that GW-level pulses of a few femtosecond duration or shorter can be produced using electron beams of quite moderate parameters and undulators of 20-m length or shorter. The output pulse is significantly shifted i...
متن کاملCoherent excitation of shake-up states in rare gas atoms by attosecond xuv pulses
In a recent experiment [2], Uiberacker et al. exposed neon atoms to a phase-stabilized fewcycle infrared (IR) laser field and a synchronized attosecond XUV pulse. The XUV pulse leads to single ionization of the Ne atom and the creation of excited (shake-up) states in the residual Ne ion. The IR pulse can then further ionize the Ne ion, thus serving as a probe for the quantum state of the singly...
