    Sammanfattning : Decision‐makers in organisations and businesses make numerous decisions every day, and these decisions are expected to be based on facts and carried out in a rational manner. However, most decisions are not based on precise information or careful analysis due to several reasons. People are, e.g. LÄS MER

  4. 24. Temporal Aspects of High-Intensity Laser-Matter Interactions

    Detta är en avhandling från Department of Physics, Lund University

    Författare :Johan Mauritsson; Lund University.; Lunds universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Particle Acceleration; Laser technology; Relativistic Self-Focusing; High-Intensity Lasers; Attosecond Pulses; Pulse Characterization; XUV; High-Order Harmonics; Ultrashort Pulses; Laserteknik; Atom- och molekylärfysik; Atomic and molecular physics; Fysicumarkivet A:2003:Mauritsson;

    Sammanfattning : The availability of short-pulse, high-intensity lasers has opened doors to new areas in atomic and plasma physics. The short pulses (a few femtoseconds), that are available today, enable unprecedented temporal measurements, while the high peak power accessible (several terawatts) allows physicists to study the interaction between light and relativistic plasmas.
