  1. 1. Resonance-enhanced Second Harmonic Generation from spherical microparticles in aqueous suspension

    University dissertation from Stockholm : AlbaNova universitetscentrum (Tills m KTH)

    Author : Sviatlana Viarbitskaya; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nonlinear optics; second harmonic generation; adsorption; molecules; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physics; fysik;

    Abstract : Second harmonic generation (SHG) is a nonlinear optical effect sensitive to interfaces between materials with inversion symmetry. It is used as an effective tool for detection of the adsorption of a substance to microscopic particles, cells, liposomes, emulsions and similar structures, surface analysis and characterization of microparticles.

  2. 2. Second-generation High-Order Harmonic Sources — From CPA to OPCPA

    University dissertation from Stockholm : AlbaNova universitetscentrum (Tills m KTH)

    Author : Piotr Rudawski; Lunds universitet.; Lund University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optical parametric chirped pulse amplification; Fysicumarkivet A:2014:Rudawski; Chirped pulse amplification; High-order harmonic generation; Attosecond pulse;

    Abstract : This thesis presents two sources of extreme ultraviolet (XUV) radiation based on high-order harmonic generation (HHG) in gases. The sources were developed for experiments requiring high-flux harmonic beams or HHG pulses at high-repetition rate. These were used experimentally to image nano-scale objects. READ MORE

  3. 3. Piezoelectric Generation and Damping of Extensional Waves in Bars

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anders Jansson; Uppsala universitet.; [2007]
    Keywords : Technology; Piezoelectric; wave; generation; damping; bar; TEKNIKVETENSKAP;

    Abstract : This thesis focuses on the electromechanical processes of generation and damping of transient waves in bars with attached piezoelectric members. In particular, the influence of amplifier and electrical circuitry on the mechanical waves is of interest. READ MORE

  5. 5. Scaling and Gating Attosecond Pulse Generation

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

    Author : Christoph Heyl; Lunds universitet.; Lund University.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coherent imaging; Ultrafast electron dynamics; Single attosecond pulses; Attosecond pulse trains; XUV sources; High-order harmonic generation; XUV frequency combs; Fysicumarkivet A:2014:Heyl;

    Abstract : Popular Abstract in English This thesis is concerned with the efficient generation of ultra-short light pulses, far beyond the visible spectral range. Such light pulses can reach durations below 100 attoseconds, where one attosecond is one billionth of a billionth of a second. READ MORE
