Generation of coherent short-wavelength radiation --- High-order harmonics and x-ray lasers

Starczewski, Tomas LU (1997)
Abstract (Swedish)
Popular Abstract in Swedish

Den senaste utvecklingen av högintensitetslasrar har gjort det möjligt att studera nya fascinerande områden inom atomfysik.



Två fenomen har studerats med Lunds Terawattlaser i intensitetsområdet 10<sup>13</sup>--10<sup>17</sup> W/cm2: förstärkning av den spontana emissionen i plasmor från fasta strålmål och gasstrålmål, samt generering av övertonsstrålning av höga ordningar.



Med hjälp av dessa fenomen kan källor av koherent, kortvågig strålning bli konstruerade. Dessa källor är mycket eftertraktade i många vetenskapliga och industriella tillämpningar.
Abstract
The recent availability of short-pulse, high-intensity, compact lasers has opened doors to new and fascinating areas in atomic physics. Using the Lund Terawatt Laser, the interaction of femtosecond, near-infrared and visible laser radiation with matter at intensities in the range 10<sup>13</sup>--10<sup>17</sup> W/cm2 was studied.



Out of many phenomena that occur in this intensity range, this thesis deals with two: the short-wavelength amplification of the spontaneous emission in plasmas created from solid and gas targets, and the generation of high-order harmonics of the fundamental laser frequency. Both phenomena can serve as a basis for the generation of short-wavelength, coherent radiation,... (More)
