1. Blue Laser Source for Laser-Induced Fluorescence
Abstract : Laser-induced fluorescence is a clinical diagnostic tool, used for tumor demarcation and detection. The technique relies on the injection or topical application of a light sensitive drug called a photosensitizer. This substance has the ability to be accumulated to higher concentrations in cancer cells than in normal cells. READ MORE

2. Optically pumped semiconductor disk lasers for high-power wide wavelength tuning
Abstract : In this work I present and verify a strategy that makes it possible to change the wavelength, or color, of an external cavity semiconductor laser over a very large range. This is achieved by a careful design and thorough optimization of the active component — the gain element of the laser. READ MORE

3. Design and Performance of Optically Pumped Semiconductor Disk Lasers with Wide Tuning Ranges
Abstract : In this work I present a strategy for providing the possibility to select the wavelength, or color, of a semiconductor laser over a very large range, by cleverly designing the vital part of the laser: the gain element of a so called optically pumped semiconductor disk laser. Optically pumped semiconductor disk lasers (OP-SDLs) are a relatively new class of lasers showing great promise for future applications. READ MORE

4. On diode-pumped solid-state lasers
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. Compact solid-state lasers in the near-infrard and visible spectral range
Abstract : 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. READ MORE
