  2. 1. Blue Laser Source for Laser-Induced Fluorescence

    Author : Jesper Holm; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Second Harmonic Generation; Lasers; PPKTP; ALA; Tapered laser diodes; External cavity lasers; Laser-induced fluorescence; photodynamic therapy; mTHPC;

    Abstract : Laser-induced fluorescence is a clinical diagnostic tool, used for tumor demarcation and detection. The technique relies on the injection or topical application of a light sensitive drug called a photosensitizer. This substance has the ability to be accumulated to higher concentrations in cancer cells than in normal cells. READ MORE

  4. 2. Development and Application of Laser-Induced Emission Techniques for Combustion Diagnostics -High-Resolution Visualization of Turbulent Reacting Flows

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser-Induced Phosphorescence; Laser Combustion Diagnostics; Non-linearity; Image Intensifier; Two-color Ratio; Lifetime Decay; Precision; Thermographic Phosphors; Temperature measurements; Fysicumarkivet A:2012:Lindén;

    Abstract : Temperature is one of the most fundamental parameters to be measured in many research disciplines. In combustion science, a thorough knowledge of temperature is essential for improving and optimizing combustion processes. READ MORE

  6. 4. Laser induced effects in carbon nanotubes : implications for Raman characterization of functionalized systems

    Author : David Olevik; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

    Abstract : Carbon nanotubes (CNTs) have attracted attention over the past decade because of their outstanding mechanical and electronic properties. These tiny tubular shells made of carbon atoms can be metallic or semiconducting and while having diameters of only about one nanometer (10-9 m), they can be up to centimeters in length, making them quasi one-dimensional (molecular wires).

  7. 5. Laser-Induced Emission Techniques for Concentration and Temperature Probing in Combustion

    Author : Gustaf Särner; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermographic phosphor; phosphor; phosphorescence; Laser Combustion Diagnostics; Laser-Spectroscopy; LIF; spectroscopy; Thermometry; LIP; Laser-Induced Fluorescence;

    Abstract : The work in this thesis is aimed at the development of temperature and gas concentration measurement techniques in laser diagnostics for use in combustion research. The techniques are developed as tools for the combustion community to meet future demands on combustion efficiency and legislation of exhaust gases. READ MORE
