  1. 16. Optically poled fibers for electro-optic applications

    Författare :Joao Manoel Barbosa Pereira; Fredrik Laurell; Walter Margulis; Stavros Pissadaki; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : The work presented in this thesis shows the development of optically poleddevices for use in electro-optic experiments. In the form of papers published,it describes three optical poling methods: green light poling (Paper I), poling with a UV lamp (Paper II), and corona discharge poling (Paper V). LÄS MER

  3. 17. Fabrication of periodically poled crystals from the KTP family and their applications in nonlinear optics

    Författare :Håkan Karlsson; KTH; []
    Nyckelord :;

    Sammanfattning : Quasi-phasematched (QPM) nonlinear optical frequencyconversion is a powerful tool in the development of new lasersources, by providing high conversion efficiency and largeflexibility in terms of output wavelengths.QPM structures are preferably implemented in bulk crystalsbe periodic electric field poling.

  4. 18. Studies on Domain Dynamics in Nonlinear Optical Ferroelectric Oxide Crystals

    Författare :Hoda Kianirad; Fredrik Laurell; Carlota Canalias; Sakellaris Mailis; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Sammanfattning : Nonlinear optical frequency conversion is the key technology for modifying laser output radiation, in order to target specific applications. The most powerful technique to obtain tailored second-order nonlinear interactions is the quasi-phasematching (QPM) approach. LÄS MER

  5. 19. Musculoskeletal Biomechanics in Cross-country Skiing

    Författare :L. Joakim Holmberg; Anders Klarbring; Hans-Christer Holmberg; Anders Eriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Why copy the best athletes? When you finally learn their technique, they may have already moved on. Using muscluloskeletal biomechanics you might be able to add the "know-why" so that you can lead, instead of being left in the swells. LÄS MER

  7. 20. Towards the production of conductive and piezoelectric bicomponent textile fibres

    Författare :Erik Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polypropylene; Graphite nanoplatelets; bi-component fibres; rheology; conductive fibres; carbon black; PVDF; electrical conductivity; piezoelectric fibres; melt spinning;

    Sammanfattning : In the present study electrical conductive and piezoelectric textile fibres have been manufactured and characterized. Potential applications of these fibres are for example textiles with heating and sensor properties. LÄS MER
