5. 19. Characterisation and Applications of Ultrashort Extreme Ultraviolet Pulses

   Författare :Johan Norin; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ultrashort pulses; pulse characterisation; sidebands; interferometry; Atom- och molekylärfysik; acetylene; Atomic and molecular physics; High-order harmonics; XUV; Fysicumarkivet A:2002:Norin;

   Sammanfattning : When a strong laser field interacts with free atoms, harmonics up to very high orders are created. This extreme ultraviolet (XUV) radiation has interesting properties, such as spatial and temporal coherence, short pulse duration and high brightness. This thesis concentrates on the temporal aspects of this radiation. LÄS MER
