  4. 3. Optically pumped semiconductor disk lasers for high-power wide wavelength tuning

    Författare :Carl Borgentun; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; beam characterization; design; high power; wavelength tuning; Semiconductor laser; gain measurements; vertical-external-cavity surface-emitting laser; optically pumped semiconductor disk laser;

    Sammanfattning : In this work I present and verify a strategy that makes it possible to change the wavelength, or color, of an external cavity semiconductor laser over a very large range. This is achieved by a careful design and thorough optimization of the active component — the gain element of the laser. LÄS MER

  7. 5. Fine-scale morphology and spectral characteristics of active aurora

    Författare :Hanna Dahlgren; Göran Marklund; Nickolay Ivchenko; Kari Kaila; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aurora; Space physics; Rymdfysik;

    Sammanfattning : Ground-based and in-situ observations of the aurora demonstrate an extreme richness in fine structure, with spatial scales down to tens of metres and time variations occurring on a fraction of a second. To further our understanding of the aurora, it is esssential to understand the mechanisms responsible for the small-scale structuring, since this is an intrinsic property of the auroral plasma.
