  2. 11. Environmental Monitoring by Multi-Spectral Lidar Techniques

    Author : Petter Weibring; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-linear optics; fluorescence spectroscopy; scattering; multi-spectral imaging; Atom- och molekylärfysik; atmospheric pollution; Atomic and molecular physics; laser; remote sensing; lidar; DIAL; Fysicumarkivet A:2002:Weibring;

    Abstract : Multi-spectral lidar (light detection and ranging) techniques have been developed and employed in various environmental studies, ranging from concentration mapping of volcanic emissions to fluorescence imaging of historical monuments. In both absorption measurements of gaseous species and fluorescence imaging of stones, multiple wavelength excitation and multiple wavelength detection have been applied. READ MORE

  4. 12. Short-Pulse Laser Spectroscopy for Combustion Diagnostics - Laser-Induced Fluorescence of Polyatomic Molecules and Developments in Measurement and Evaluation

  7. 15. Quantum Optics and Waveguide Quantum Electrodynamics in Superconducting Circuits

    Author : Emely Wiegand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Quantum Optics; Circuit Quantum Electrodynamics; Waveguide Quantum Electrodynamics; Superconducting Qubits; Artificial Atoms;

    Abstract : Waveguide circuit quantum electrodynamics (waveguide circuit QED) studies light-matter interaction with superconducting circuits in one dimension. In circuit QED, natural atoms are replaced by superconducting qubits consisting of a non-linear Josephson junction, resulting in an anharmonic energy spectrum just like real atoms. READ MORE
