    Sammanfattning : Optical parametric oscillators (OPOs) and optical parametricamplifiers (OPAs) constitute a class of optical frequencyconverting devices that have many possible applications, e.g.in range finding, molecular spectroscopy and medicine. LÄS MER

  4. 33. 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
