  1. 1. Ultrafast opto-optical control of extreme ultraviolet light pulses

    Författare :Samuel Bengtsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; extreme ultraviolet; controlled emission; Free induction; time-dependent spectroscopy; noble; High order harmonic generation; phase-control; Fysicumarkivet A:2017:Bengtsson;

    Sammanfattning : Extreme ultraviolet (XUV) light is a valuable frequency range for ultrafast optics experiments. The short wavelength is a requirement for ultrashort pulses, which are widely used to characterize fast dynamics. Additionally, the high photon energy enables quantum control of high frequency transitions in atoms. LÄS MER

  3. 2. Material and technique development for ultrasound optical tomography using spectral hole burning filters

    Författare :Alexander Bengtsson; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomedical imaging; ultrasound optical tomography; acousto-optical tomography; rare-earth-ion doped crystals; spectral holeburning; slow light filters; Tm 3:LaF3; Fysicumarkivet A:2022:Bengtsson;

    Sammanfattning : The molecular sensitivity provided by optical photons has potential advantages in medical diagnostics, for example, in distinguishing healthy from cancerous tissue. However, scattering resulting from inhomogeneities in the refractive index of tissues prevents spatially resolved optical measurements in biological material, except at very shallow depths. LÄS MER

  4. 3. Time-Resolved X-ray Diffraction Studies of Laser-Induced Dynamics in Solids

    Författare :Åsa Bengtsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-resolved X-ray diffraction; ultrafast; phonons; pressure wave; Non-thermal melting; Fysicumarkivet A:2022:Bengtsson;

    Sammanfattning : X-ray diffraction is an invaluable tool in the field of structural dynamics. In the work described in this thesis, time-resolved X-ray diffraction experiments were carried out to investigate ultrafast lattice dynamics. LÄS MER

  7. 5. Karriär och profession. : Om positioner, statushierarki och mobilitet inom socionomyrket

    Författare :Mikael Bengtsson; Socialhögskolan; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Profession; yrke; professionalism; intraprofessionell; karriär; socialt arbete; socionom; differentiering; position; status; stratifiering; mobilitet; Profession; occupation; professionalism; intraprofessional; career; social work; differentiation; position; status; stratification; mobility;

    Sammanfattning : Societal reforms and development within the Swedish public sector have reframed the prerequisites for social workers, and other professions, and changed the area of work practice. I have used the career concept in order to investigate professional change because it provides a conceptual lens to illuminate stability and change and it captures both external and internal professional processes.
