  1. 1. Characterisation and Applications of Ultrashort Extreme Ultraviolet Pulses

    University dissertation from Atomic Physics, Department of Physics, Lund University

    Author : Johan Norin; Lunds universitet.; Lund University.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ultrashort pulses; pulse characterisation; sidebands; interferometry; Atom- och molekylärfysik; acetylene; Atomic and molecular physics; High-order harmonics; XUV; Fysicumarkivet A:2002:Norin;

    Abstract : When a strong laser field interacts with free atoms, harmonics up to very high orders are created. This extreme ultraviolet (XUV) radiation has interesting properties, such as spatial and temporal coherence, short pulse duration and high brightness. This thesis concentrates on the temporal aspects of this radiation. READ MORE

  3. 3. Mid- and near-infrared NICE-OHMS techniques for ultra-sensitive detection of molecules in gas phase

    University dissertation from Umeå : Umeå universitet

    Author : Thomas Hausmaninger; Umeå universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spectrometry; NICE-OHMS; trace gas detection; acetylene; methane; isotopologues; near-infrared; mid-infrared; shot-noise; optical parametric oscillator; Technical Physics; teknisk fysik med inriktningen mikrosystemteknik;

    Abstract : Noise-immune cavity-enhanced optical heterodyne molecular spectrometry (NICE-OHMS) is a technique for ultra-sensitive detection of molecular absorption and dispersion. For highest performance, the technique combines cavity enhancement (CE) with frequency modulation (FM); while the former increases the effective interaction length between the light and the analyte by several orders of magnitudes, the latter removes the in-coupling of 1/f noise and makes the signals background free.
