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. Novel Technologies for Mode-Locking of Solid-State Lasers

   Author : Niels Meiser; Valdas Pasiskevicius; Steinmeyer Günter; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; laser; mode-locked laser; pulsed laser; quantum dot; carbon nanotube; nonlinear optics; saturable absorber; Kerr-lens mode-locking; ultra-fast laser; picosecond laser; pulsed laser; semiconductor saturable absorber;

   Abstract : The subject of this thesis is the investigation of novel technologies for mode-locking of diode-pumped, solid-state lasers. Novel saturable absorbers are used: quantum dots (QDs) and carbon nanotubes (CNTs), which both are low-dimensional nano-formations. In addition, mode-locking by cascaded nonlinearities is explored.

6. 4. 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

7. 5. 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
