  1. 1. Laser-Produced Plasmas for Particle Acceleration

    Författare :Kristoffer Svensson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis describes experimental studies that aim to stabilise and optimise laser-based particle accelerators. The technique is called laser wakefield acceleration, where electric fields of the order of 102 GV/m accelerate electrons to high energies (⇠102 MeV) over mm-distances in laser-produced plasmas.

  4. 3. Laser-Matter Interactions at Extreme Irradiance: X-ray Generation and Relativistic Channelling

    Författare :Anders Sjögren; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relativistic self-focusing; particle acceleration; x-ray generation; radiography; Laserteknik; Laser technology; laser-produced plasma; light scattering; Fysicumarkivet A:2002:Sjögren;

    Sammanfattning : This thesis summarizes experimental work in which the powerful Ti:sapphire lasers at the High Power Laser Facility at the Lund Laser Centre have been employed to investigate laser-produced X-rays and relativistic channelling. These lasers produce short pulses, of the order of 50 fs, with energies ranging from 1 mJ to 1 J. LÄS MER

  5. 4. A new laser-plasma X-ray source for microscopy and lithography

    Författare :Lars Rymell; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; X-ray lithography; Atomic and molecular physics; multilayer mirror; Fysicumarkivet A:1997:Rymell; Atom- och molekylärfysik; X-ray source; Laser-produced plasma; liquid droplet; debris-free; water window;

    Sammanfattning : A new high-brightness source for soft X-rays and EUV-radiation has been developed. This laser-plasma source utilizes a microscopic liquid droplet or jet as target. The result is a reduction of debris emission by several orders of magnitude compared to conventional laser plasmas. LÄS MER

  7. 5. Temporal Aspects of High-Intensity Laser-Matter Interactions

    Författare :Johan Mauritsson; Atomfysik; []
    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.
