  2. 1. Photoluminescence-based characterization of bioengineered nanovesicles and erbium emitters

    Author : Maryam Sanaee; Katia Gallo; Jerker Widengren; Martin Hof; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioengineered nanovesicles; Coincident fluorescent burst analysis; Drug loading; Erbium emitters; Lithium niobate; Photoluminescence.; Bioingenjörskonstruerade nanovesiklar; Analys av sammanfallande fluorescerande blossteknik; Läkemedelslastning; Erbium-emitterare; Lithium niobate; Fotoluminiscens.; Biologisk fysik; Biological Physics; Optics and Photonics; Optik och fotonik;

    Abstract : In recent decades, photoluminescence properties of single molecules and ions have opened new possibilities for studies on smaller size scales, below the light-diffraction limit. In this thesis, the advantages of such single photon emitters were harnessed and studied mainly in the field of biophysics, but also, in investigations within solid state photonics. READ MORE

  4. 2. On diode-pumped solid-state lasers

    Author : Jonas Hellström; Fredrik Laurell; Valdas Pasiskevicius; Klaus Petermann; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; near-infrared lasers; end-pumped lasers; Q-switching; erbium; ytterbium; GdCOB; KGW; KYW; Co:MALO; laser materials; thermal lensing; end-pumping; spectroscopy; conical refraction; volume Bragg gratings; holographic gratings; laser tuning; Physics; Fysik;

    Abstract : The research that is presented in this thesis can be divided into two major parts. The first part concerns longitudinally pumped, bulk Er-Yb lasers. In these lasers, the main limitation is the thermal shortcomings of the phosphate glass host material. READ MORE

  5. 3. Spectral control of lasers and optical parametric oscillators with volume Bragg gratings

    Author : Björn Jacobsson; Fredrik Laurell; Uwe Morgner; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; volume Bragg gratings; single-longitudinal-mode laser; laser tuning; erbium; neodymium; ytterbium; nonlinear optics; optical parametric oscillator; KTP; tunable optical parametric oscillator; narrowband optical parametric oscillator; Physics; Fysik;

    Abstract : I den här avhandlingen visas hur lasrar och optiska parametriska oscillatorer (OPO:er) kan styras spektralt med hjälp av volymbraggitter. Volymbraggitter utgörs av ett periodiskt varierande brytningsindex som skrivits i ett fototermorefraktivt glas. READ MORE

  6. 4. Collectivity in Neutron-Rich Erbium Isotopes

    Author : Aila Gengelbach; Johan Nyberg; Lantz Mattias; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear structure; collective excitations; rare-earth nuclei; gamma-ray spectroscopy; AGATA; PRISMA; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Abstract : Neutron-rich rare-earth nuclei around the maximum of collectivity are predicted to exist with an extremely stable intrinsic configuration in their ground-state structure. Due to the high degree of axial symmetry and large deformation, these nuclei are also excellent candidates for having long-lived high-K isomers. READ MORE

  7. 5. Synthesis and characterisation of heterobimetallic erbium alkoxides

    Author : Maria Wijk; Jean Galy; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : This thesis describes the synthesis and characterisation of alkoxides in the Er-M systems, where M = Al, Ti and Zr. The compounds found have been characterised by IR, UV-Vis DSC and single-crystal X-ray diffraction techniques and by chemical behaviour. READ MORE
