Attosecond Wave Packet Metrology - AVHANDLINGAR.SE

We use two synchronised laser pulses with a precisely controlled time-delay to record movies of electrons in motion. Ferenc Krausz from the Max Planck Institute of Quantum Optics in Munich is considered the founder of attosecond physics. His goal is to develop new laser tec The CFEL-ATTO group collaborated in experiments aimed at controlling the ionization of LiNbO 3 with strong-field lasers, gaining new insights on the role of microscopic material properties in this fundamental process through femtosecond laser-ablation, a technique often employed in high-resolution micromachining of materials. We use a train of sub-200 attosecond extreme ultraviolet (XUV) pulses with energies just above the ionization threshold in argon to create a train of temporally localized electron wave packets. We study the energy transfer from a strong infrared (IR) laser field to the ionized electrons as a function of the delay between the XUV and IR fields.

2021-01-29 Recent progress in sub-laser-cycle gating of high-order harmonic generation promises to push the limits on optical pulse durations below the atomic unit of time, 24 as, which corresponds to a bandwidth broader than 75 eV. However, the available techniques for attosecond pulse measurement are valid only for narrow-bandwidth spectra, due to one of the key approximations made in the phase retrieval. Anyone interested in Attosecond science is welcome to join! The Lund Attoscience Symposium 2021 will offer monthly two-hour sessions on Wednesdays from 16.00 to 18.00.

Rob van den Berg spoke to Ferenc Krausz and Reinhard Kienberger, two pioneers in attosecond physics, about their work. Pris: 1999 kr. Häftad, 2010.
