    Sammanfattning : The subject of this thesis is the exploration of new concepts for compact solid-state lasers in the visible and near-infrared spectral range using new components such as volume Bragg gratings for wavelength stabilisation and wavelength tuning. Also single-walled carbon nanotubes for mode-locking and Q-switching of lasers have been studied. LÄS MER

  3. 2. Spectral control of lasers and optical parametric oscillators with volume Bragg gratings

    Sammanfattning : I den här avhandlingen visas hur lasrar och optiska parametriska oscillatorer (OPO:er) kan styras spektralt med hjälp av volymbraggitter. Volymbraggitter utgörs av ett periodiskt varierande brytningsindex som skrivits i ett fototermorefraktivt glas. LÄS MER

  4. 3. Diode-pumped rare-earth-doped quasi-three-level lasers

    Författare :Stefan Bjurshagen; Fredrik Laurell; Markus Pollnau; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optics; laser optics; Physics; Fysik;

    Sammanfattning : Many rare-earth-doped materials are suitable for laser operation and this thesis focuses on diode-pumped solid-state lasers employing crystals doped with the trivalent rare-earth ions neodymium (Nd3+), ytterbium (Yb3+) and erbium (Er3+). Especially, the quasi-three-level transitions in Nd and Yb have been studied as well as the eye-safe three-level transition around 1. LÄS MER

  5. 4. Diode-pumped Nd : YAG lasers for generation of blue light by frequency doubling

    Författare :Stefan Bjurshagen; KTH; []
    Nyckelord :;

    Sammanfattning : Quasi-three-level lasers in neodymium-doped crystals such asNd:YAG, Nd:YLF and Nd:YVO4have received a great deal of interest becausethey allow generation of blue light by frequency doubling. Forsolid-state blue laser sources, there exist numerousapplications as in high-density optical data storage, colourdisplays, submarine communication and biologicalapplications. LÄS MER
