  2. 6. Continuously tunable narrow-linewidth fiber lasers

    Author : Xiong Yang; Valdas Pasiskevicius; Fredrik Laurell; Magnus Engholm; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fiber laser; Optik och fotonik; Optics and Photonics;

    Abstract : Narrow linewidth tunable fiber lasers have become an important tool in research and in-field applications thanks to their high beam quality, great spectral performance, compact structure and environmental robustness. Many methods have been introduced and developed throughout decades to fulfill the need for rapid wavelength adjustment of these fiber lasers. READ MORE

  4. 7. Laser spectroscopic analysis of atmospheric gases in scattering media

    Author : Mikael Sjöholm; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fjärranalys; Remote sensing; Laser spectroscop; Scattering of light; Diode lasers; acoustics; optics; Electromagnetism; optik; akustik; Elektromagnetism; Optical absorption; Nondestructive testing: optical; Interdisciplinary applications of physics; Laser technology; Atom- och molekylärfysik; Atomic and molecular physics; LIDAR remote sensing; Laserteknik;

    Abstract : Laser spectroscopic techniques for gas analysis under various influences of light scattering are explored in a wide spectral range from the ultraviolet to the infrared. The techniques rely on spectrally narrow-band light sources that are used in differential optical absorption measurements. READ MORE

  5. 8. Development of Lidar Techniques for Environmental Studies

    Author : Mats Andersson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The lidar group in Lund has performed many DIAL measurements with a mobile lidar system that was first described in 1987. The lidar system is based on a Nd: YAG-pumped dye laser. During the last few years the lidar group has focused on fluorescence imaging and mercury measurements in the troposphere. READ MORE

  6. 9. Diode-laser absorption spectroscopy - applications in medicine and environmental monitoring

    Author : Jim Larsson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TDLAS; GASMAS; biophotonics; Scheimpflug Lidar; Fysicumarkivet A:2019:Larsson;

    Abstract : A major part of this thesis work has been research in a medical project, where, together with industry and clinical partners, the aim was to develop a prototype system for non-invasive monitoring of premature babies based on the optical measurement technique gas in scattering media absorption spectroscopy (GASMAS). Part of the project was to develop a 3D-printed tissue phantom based on chest X-ray images of the thorax of a premature infant. READ MORE

  7. 10. Application of Laser Techniques for Combustion Studies

    Author : Marcus Aldén; Fysiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Keywords: Laser-induced fluorescence; Raman Spectroscopy; Coherent anti-Stokes Raman Scattering CARS ; flames; laserspectroscopy; dye laser; lidar; remote sensing; combustion; air pollution; radicals; optical multichannel analyzer.; Fysicumarkivet A:1983:Aldén;

    Abstract : The aim for this work has been to increase the applicability of laser spectroscopy techniques for studies of combustion processes, both what regards in-flame experiments, exhaust-gas analysis and remote sensing of the atmosphere. Raman spectroscopy has been used for analysis of exhaust gases from flames, model fires of wood and for inflame measurements. READ MORE
