   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; near-infrared lasers; end-pumped lasers; Q-switching; erbium; ytterbium; GdCOB; KGW; KYW; Co:MALO; laser materials; thermal lensing; end-pumping; spectroscopy; conical refraction; volume Bragg gratings; holographic gratings; laser tuning; Physics; Fysik;

   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. 2. Novel materials for Yb and Er-Yb doped microchip lasers

   Författare :Jonas Hellström; Fredrik Laurell; Lars Sjöqvist; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mid-IR lasers; laser materials; Optical physics; Optisk fysik;

   Sammanfattning : The objective of this thesis has been to investigate novel host material configurations for high-power end-pumped Er-Yb co-doped, or Yb doped microchip lasers and try to increase their performance. In Er-Yb co-doped systems, the main limitation is the thermal shortcomings of the phosphate glass host material. LÄS MER
