1. Development of Experimental Methods, Data Analysis and Standards in Atomic Spectroscopy
Sammanfattning : The focus of this work is on the experimental techniques and data analysis in atomic spectroscopy. Improved methods for the analysis of spectra and the determination of level energies are presented. Most of these are based on a rigorous statistical treatment of the spectroscopic data. LÄS MER
2. Compact solid-state lasers in the near-infrard and visible spectral range
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. On diode-pumped solid-state lasers
Sammanfattning : 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. LÄS MER
4. 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
