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

    Author : Stefan Bjurshagen; KTH; []
    Keywords : ;

    Abstract : 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. READ MORE

  4. 2. On diode-pumped solid-state lasers

    Author : Jonas Hellström; Fredrik Laurell; Valdas Pasiskevicius; Klaus Petermann; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; near-infrared lasers; end-pumped lasers; Q-switching; erbium; ytterbium; GdCOB; KGW; KYW; Co:MALO; laser materials; thermal lensing; end-pumping; spectroscopy; conical refraction; volume Bragg gratings; holographic gratings; laser tuning; Physics; Fysik;

    Abstract : The research that is presented in this thesis can be divided into two major parts. The first part concerns longitudinally pumped, bulk Er-Yb lasers. In these lasers, the main limitation is the thermal shortcomings of the phosphate glass host material. READ MORE

  5. 3. Compact diode-pumped solid-state lasers

    Author : Stefan Spiekermann; KTH; []
    Keywords : visible lasers; UV lasers; solid-state lasers;

    Abstract : Compact diode-pumped solid-state lasers (DPSSL) arecontinuously replacing traditional gas lasers as well asenabling completely new technology. However, compact and costefficient designs are required to satisfy end-user demands. Theaim of this thesis was therefore to investigate novel laserdesigns for given applications considering these demands. READ MORE

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

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

    Abstract : 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. READ MORE
