    Sammanfattning : Optical frequency combs have revolutionized the field of laser spectroscopy. A frequency comb is a type of laser that generates an array of equally spaced coherent laser lines. Indeed, the outstanding performance of frequency combs in terms of bandwidth and stability is readily attainable in bench-top systems. LÄS MER

  4. 3. Theoretical study of light-molecule nonlinear interactions

    Författare :Ke Zhao; Yi Luo; Fahmi Himo; Valdas Pasiskevicius; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioengineering; Bioteknik;

    Sammanfattning : The work presented in the thesis concerned theoretical study of light-matter nonlinear interactions. Two important aspects of such interactions have been examined, namely the nonlinear optical properties of a series of organic charge transfer molecules in solutions induced by the laser light and the propagation of the ultrafast high power laser through the nonlinear molecular medium.
