3. 2. High Performance Fiber Lasers with Spectral, Thermal and Life Time Control

   Författare :Pär Jelger; Fredrik Laurell; Johan Nilsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical physics; Optisk fysik;

   Sammanfattning : This thesis contains the results of research in the fields of spectral control, efficiency andlifetime of high-power, rare-earth doped fiber lasers, properties which are of greatimportance for scientific and industrial applications. Volume Bragg gratings (VBGs) has forthe first time been used together with fiber lasers and the laser performance in terms ofspectral purity, thermal stability, and tunability was evaluated. LÄS MER
