  2. 11. Cerium as a quantum state probe for rare-earth qubits in a crystal

    Author : Jenny Karlsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spectroscopy; Quantum Computing; Rare-earth-ion-doped crystals; Microscopy; Fysicumarkivet A:2015:Karlsson;

    Abstract : Rare-earth ions doped into a transparent crystal can have optically excited states with coherence times of milliseconds and hyperfine levels with coherence times of hours when cooled down to liquid helium temperatures. This makes them attractive for developing quantum computing hardware. READ MORE

  4. 12. Attosecond interferometry: techniques and spectroscopy

    Author : David Kroon; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2016:Kroon; Electron wave packet; Attosecond Pulse trains; Photoionization; Photoemission time delay; High-order harmonic generation; Interferometry; Electron dynamics;

    Abstract : The interaction between an intense laser pulse and a gas medium leads to the emission of coherent bursts of light in the extreme ultraviolet range. This process, known as high-order harmonic generation, has today, almost three decades after its discovery, developed into a reliable source of extremely short (on the order of 100 as) pulses of electromagnetic radiation, with a wide range of applications in the atomic, molecular and optical sciences.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photoionization; Single attosecond pulses; Attosecond pulse trains; Electron wave packet; Electron dynamics; Interferometry; Photoemission time delay; Fysicumarkivet A:2012:Klünder; Stark spectroscopy;

    Abstract : One objective of attosecond science is to study electron dynamics in atoms and molecular systems on their natural time scale. This can be done using attosecond light pulses. READ MORE

  7. 15. Nonlinear optical techniques for ultrafast laser diagnostics : Development of femtosecond LIF, LIGS, CARS and backward lasing

    Author : Maria Ruchkina; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; laser diagnostics; femtosecond laser; nonlinear interactions; ultrafast spectroscopy; multi-photon excitation; laser-induced fluorescence; rotational coherent anti-Stokes Raman spectroscopy; laser-induced grating spectroscopy; lasing; backward lasing technique; Fysicumarkivet A:2021:Ruchkina;

    Abstract : The thesis work concerns development and application of four versatile nonlinear optical techniques, based on exploiting ultrashort laser pulses, for diagnostic purposes in gases and flames. The four techniques, all laser-based, are two-photon laser-induced fluorescence (TPLIF), hybrid femtosecond/nanosecond (fs/ns) rotational coherent anti-Stokes Raman scattering (fs/ns RCARS), fs-laser-induced grating spectroscopy (fs-LIGS), and backward lasing.
