1. Constructing and Commissioning HELIOS – A High Harmonic Generation Source for Pump-Probe Measurements with sub 50 fs Temporal Resolution The Development of Experimental Equipment for Extreme Ultraviolet Spectroscopy
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : 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. Optical Frequency Comb Fourier Transform Spectroscopy
Detta är en avhandling från Umeå : Umeå UniversitetSammanfattning : Fourier transform spectroscopy (FTS) based on optical frequency combs is an excellent spectroscopic tool as it provides broadband molecular spectra with high spectral resolution and an absolutely calibrated frequency scale. Moreover, the equidistant comb mode structure enables efficient coupling of the comb to enhancement cavities, yielding high detection sensitivity. LÄS MER
3. Fourier transform and Vernier spectroscopy using optical frequency combs
Detta är en avhandling från Umeå : Umeå UniversitySammanfattning : Optical frequency comb spectroscopy (OFCS) combines two previously exclusive features, i.e., wide optical bandwidth and high spectral resolution, enabling precise measurements of entire molecular bands and simultaneous monitoring of multiple gas species in a short measurement time.

4. Development of Experimental Methods, Data Analysis and Standards in Atomic Spectroscopy
Detta är en avhandling från Lund Observatory, Lund UniversitySammanfattning : The focus of this work is on the experimental techniques and data analysis in atomic spectroscopy. Improved methods for the analysis of spectra and the determination of level energies are presented. Most of these are based on a rigorous statistical treatment of the spectroscopic data. LÄS MER
5. Laboratory and stellar spectroscopy of the complex ions Fe+, Mo+, Th+ and U+
Detta är en avhandling från Hampus Nilsson, Lund UniversitySammanfattning : The new generation of high resolution astronomical instruments such as the Hubble Space Telescope (HST) or the Very Large Telescope (VLT) has renewed the demand for accurate atomic parameters like wavelengths, oscillator strengths and line profiles accompanied by reliable uncertainty estimates. Fourier transform spectroscopy has proven to be a powerful tool when measuring these parameters. LÄS MER
