  1. 11. High Power, Long Wavelength Semiconductor Disk Lasers for Continuous and Mode-Locked Operation

    Författare :Hans Lindberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mode-locking; thermal management; spectral properties; optically pumped; single frequency; beam quality; vertical-external-cavity surface-emitting laser; disk laser; Semiconductor laser;

    Sammanfattning : The semiconductor disk laser has recentlyemerged as an attractive alternative to bulky and power consuming gas and solid state lasers. It offers compact, powerful and efficient devices with W level output power and beam properties earlier not achieved with semiconductor lasers. LÄS MER

  3. 12. Dendron decorated chromophores for optical power limiting applications

    Författare :Robert Vestberg; KTH; []
    Nyckelord :Life sciences and physical sciences; polymer chemistry; optics physics; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The need for protection of eyes and electro-optic sensors from powerful lasers has increased the need for new and better optical power limiting (OPL) materials that can protect against laser light. In this study the synthesis and characterization of dendron-coated OPL chromophores (porphyrins, thiophenes, and platinum(II) acetylides) are discussed. LÄS MER

  4. 13. Structure-Property-Composition Correlations in Rare-Earth Alumino-silicate Glasses

    Författare :ANM Shahriar Iftekhar; Mattias Edén; Jekabs Grins; Bo Jonson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Rare earth (RE) alumino-silicate (AS) glasses exhibit favorable physical, mechanical and optical properties, such as high values of the glass transition temperature, Vickers hardness, and refractive index. RE2O3-Al2O3-SiO2 glasses have found several industrial applications, for example as components of optical amplifiers and lasers. LÄS MER

  5. 14. Optical Functionalization of Transparent Wood Biocomposites

    Författare :Martin Höglund; Lars Berglund; Sergei Popov; Jonsson Magnus; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transparent wood; biocomposite; optical scattering; interfaces; dye laser; organic dye; plasmonic; nanoparticle;

    Sammanfattning : Transparent wood (TW) biocomposites combines load-bearing properties with high transmittance of light. TW consists of a reinforcing wood substrate that has been infiltrated with a polymer matrix. TW can be combined with additives so that new multifunctional materials are obtained. LÄS MER

  7. 15. Nonlinear Absorbing platinum(II) Acetylides for Optical Power Limiting Applications

    Författare :Robert Westlund; Eva Malmström; Sergei Vinogradov; KTH; []
