  1. 1. Development of Spectroscopic Measurements for Raman and Thomson Scattering Diagnostics ——Applications in Combustion and Plasma

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Miaoxin Gong; [2019]
    Keywords : Raman scattering; Raman spectroscopy; Thomson scattering; stray light suppression; periodic shadowing; high dynamic range imaging; digital micro-mirror device; DMD; laminar flames; combustion; gas discharge; plasma; laser diagnostics; spectrometer; improved spectroscopy; spectroscopy; Physics and Astronomy;

    Abstract : This thesis work concerns methods for improved spectroscopy including stray-light suppression, dynamic range improvement and signal enhancement. These methods were applied in Raman and Thomson- scattering spectroscopy in combustion and plasma. READ MORE

  2. 2. The Spatial Properties of the Beam Profile of an OPCPA

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Mattias Bengtsson; [2019]
    Keywords : Laser; OPCPA; Imaging Spectrometer; Physics and Astronomy;

    Abstract : OPCPA stands for optical parametric chirped-pulse amplification. It is a nonlinear method for amplifying broadband laser beams. The spatial properties of the output of the laser beam depends on the amplification method itself and the broadband configuration. READ MORE

  3. 3. UAV based hyperspectral grassland monitoring in an alpine shallow erosion area : lessons learnt from classifying vegetation indicating shallow erosion risk

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : John Peitz; [2019]
    Keywords : Physical Geography; Ecosystem Analysis; Shallow Erosion; Blaiken; UAV; Hyperspectral Imaging; Alps; Grassland; Spectral Signatures; Geomatics; Earth and Environmental Sciences;

    Abstract : UAV based hyperspectral grassland monitoring in an alpine shallow erosion area Recent research in the Alps found that a reduction in grassland management is correlated to an increase in a certain type of shallow erosion areas called blaiken. This change also entails changes to the dominant grassland vegetation. READ MORE

  4. 4. All solid state single-shot Dispersion scan (D-Scan) for ultrashort laser pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Shekhar Jadhav; [2019]
    Keywords : Dispersion scan; d-scan; Single shot d-scan; Si-scan; Physics and Astronomy;

    Abstract : Ultrashort laser pulses play an important role in many applications in science and technology, from attosecond science to time resolved spectroscopy and material processing. For applications of ultrashort laser pulses, it requires a complete characterization of the electric field of the pulse, which includes both phase and amplitude of the electric field. READ MORE

  5. 5. Photoionization study using few attosecond pulses and coincidence imaging techniques

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Lisa Rämisch; [2019]
    Keywords : Laser spectroscopy; Attosecond Science; Electron Spectroscopy; Physics and Astronomy;

    Abstract : Photoionization is one of the most fundamental photoreactions that leads to the ejection of an electron and the formation of an ion. With the help of modern 3D momentum imaging spectrometers, the interplay between the time and frequency domain upon ionization is studied. READ MORE
