    Abstract : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.

  2. 2. Time-Resolved Spectroscopy for Pharmaceutical Applications

    Author : Christoffer Abrahamsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Elektromagnetism; optik; Near-infrared spectroscopy; Time-resolved spectroscopy; Pharmaceutical analysis; Multivariate data analysis; Electromagnetism; Light transport in turbid media; Photon migration; akustik; acoustics; optics;

    Abstract : The work presented in this thesis aims at improving spectroscopic techniques for analysis of pharmaceutical solids. This improvement is achieved by the combining and development of instrumentations and data evaluation tools from two research fields: the fields of near infrared spectroscopy and biomedical optics.

  3. 3. Time resolved molecular laser spectroscopy

    Author : Peter Weijnitz; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : A number of experimental and theoretical schemes have been employed to perform time resolved investigations on diatomic molecules. Laser excitation of the molecule in question is the common ground in the cases discussed. READ MORE

  4. 4. Time Resolved Diffraction Studies of Structural Changes in Sensory Rhodopsin
