   Sammanfattning : White-light spectra of different crystals, based on 1030-nm intense pump pulses have been investigated in order to derive a near-infrared seed for mid-infrared generation. Among ten crystals, YAG (yttrium aluminium garnet), KGW (potassium gadolinium tungstate) and YVO4 (yttrium orthovanadate) exhibit the most suitable properties for supercontinuum generation with high efficiency for spectral broadening as well as high tolerance to optical damage.

   Sammanfattning : The purpose of this thesis was to investigate the possibilities of enhancing the temporal and spatial coherence of parametric devices in the mid-infrared spectrum by exploiting inherent coherence selection of Bessel beams. Several optical parametric oscillators (OPO) were constructed and characterized for various types of resonators and pump lasers. LÄS MER
