  1. 11. Diode-pumped Nd : YAG lasers for generation of blue light by frequency doubling

    Författare :Stefan Bjurshagen; KTH; []
    Nyckelord :;

    Sammanfattning : Quasi-three-level lasers in neodymium-doped crystals such asNd:YAG, Nd:YLF and Nd:YVO4have received a great deal of interest becausethey allow generation of blue light by frequency doubling. Forsolid-state blue laser sources, there exist numerousapplications as in high-density optical data storage, colourdisplays, submarine communication and biologicalapplications. LÄS MER

  3. 12. High Temperature Superconducting and Tunable Ferroelectric Microwave Devices

    Författare :Erik F. Carlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; varactors; tunable microwave circuits; conformal mapping; cryogenic probe station; ferroelectrics; high temperature superconductors; microwave circuits; narrow-band filters; phase-shifter;

    Sammanfattning : This thesis addresses some applications of High Temperature Superconductors (HTS) and ferroelectric materials in tunable microwave devices and circuits. The work is divided into three main areas: i) modeling of multilayered structures including ferroelectric layers, ii) realization and characterization of tunable coplanar waveguides (CPW), capacitors and resonators based on ferroelectrics, and iii) an investigation of microstrip HTS K-band filters.

  4. 13. Web-based learning design in paediatric perioperative care : the importance of including an educational framework and children’s own perspectives

    Författare :Gunilla Lööf; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The perioperative period is a significant and unforgettable life event for children with both short-term and long-term effects. Despite evidence highlighting the importance of including children’s perspectives, their right to and need for preparation, children’s views of the perioperative period are rarely sought and many are still arriving in the operating room unprepared and with preoperative anxiety.
