1. 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
2. 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
3. Coherent CO2 laser radar in active imaging systems
Sammanfattning : .... LÄS MER
4. All-fiber modulators for laser applications
Sammanfattning : The objective of this thesis was to explore the usefulness of all-fiber modulators for laser applications. The modulators were all based on refractive index change achieved in the core of the studied fiber- components, exploiting either the elasto-optic effect or the electro-optic effect. LÄS MER
5. Stability and accuracy in microchip lasers for high precision range finding
