   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

   Sammanfattning : Crystals are beautiful, not only as pieces of jewellery, but also for their intrinsic properties, which are of significant scientific and technological importance. Ferroelectric materials are extremely versatile, since they may be combined with piezoelectric or electrooptic devices for use as filters, oscillators, memories, light detectors, and displays.
