  1. Quantum Electrodynamic Theory of Optical High-Order Harmonic Generation

    Gao, JuUniversity of Illinois at Urbana-Champaign2015

    Based on the theoretical analysis, harmonies with higher orders are predicted to be generated with higher efficiency, if a means is devised to utilize more energetic photoelectrons to the harmonic generation process.

  2. Direct Observation of Laser Filamentation in High-Order Harmonic Generation

    Painter, John Charles2006

    … of an intense laser pulse as it generates high-order harmonics in a long gas cell, filled with 80 torr of helium. A thin foil separates the gas-filled region of the cell from a subsequent evacuated region. The exit plane of the gas cell can be scanned along the laser axis so that the …

  3. Controlling Laser High-Order Harmonic Generation Using Weak Counter-Propagating Light

    Voronov, Sergei Leonidovich2002

    Laser high-order harmonic generation in the presence of relatively weak interfering light is investigated. The interfering pulses intersect the primary harmonic-generating laser pulse at the laser focus. The interfering light creates a standing intensity and phase modulation on the field, which …

  5. The Development of a Novel Femtosecond Xuv Light Source to Do Spectroscopy of Atoms and Molecules.

    Evans, Son Hoang VoThe Ohio State University1997

    … less than 100 femtoseconds and an incredible high intensity ( I >1017 watts/cm2) to be obtained. When an atomic or molecular medium is exposed to such an intense field, the interaction between the medium and the field is unique. The field will ionize and/or dissociate a molecular medium. The …

    Fulfer, Kristen D'AnnChemistry2022

    … thymine, uracil, and cytosine, is shown using high-resolution photoelectron spectroscopy. Chapters 7-8 discuss the use of elliptically polarized light for high-order harmonic generation as a probe for electron rescattering dynamics in the gas-phase medium.

    Sutherland, Julia Robin Miller2005

    … nm bandwidth) laser pulses are used to study high-order harmonic generation in helium- and neon-filled gas cells of various lengths. Harmonic orders in the range of 50 to 100 are investigated. A semi-infinite cell geometry produces brighter harmonics than cells of sub-centimeter length. In the …

  9. Scaling and Gating Attosecond Pulse Generation

    Heyl, ChristophAtomic Physics, Department of Physics, Lund University2014

    High-order harmonic generation (HHG) provides the basis for attosecond light sources delivering coherent pulses in the extreme ultraviolet spectral region. Such light sources are employed for a variety of applications within imaging, attosecond spectroscopy, and high-precision frequency metrology. …
