  1. 587. (I) Signatures of light-induced potential energy surfaces in H2+ - beyond conical intersections
    Prof. Andre Staudte (National Research Council and University of Ottawa)

    Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Invited Speaker / Conférencier(ère) invité(e)

    H2 continues to provide fundamental insights into the mechanisms of intense light-matter interactions [1]. Recently, there has been significant interest in so-called light-induced conical intersections (LICI) that arise from the angle dependence of the single-photon coupling of electronic states. Analogously to regular conical intersections, electronic and nuclear motions are strongly coupled...

  2. 588. (I) Coherent Ultrafast Electronic Dynamics in Molecules
    Prof. Albert Stolow (University of Ottawa)

    Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Invited Speaker / Conférencier(ère) invité(e)

    The non-adiabatic coupling of nuclear and electronic degrees of freedom underlies many fundamental processes in Nature, including solar energy conversion and photosynthesis. The formation of electronic coherences by nuclear motion is a new aspect of such dynamics and requires new measurement techniques and methods of analysis. We will discuss Ultrafast Time-Resolved Xray Absorption and...

  3. 233. Clocking enhanced ionization of hydrogen molecule using molecular rotational wavepackets

    Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Oral (Non-Student) / Orale (non-étudiant(e))

    Laser-induced rotational wavepacket of hydrogen molecules has been experimentally observed in real time by using two sequential 25-fs laser pulses (pump-probe scheme) and a COLTRIMs spectrometer. By measuring the time-dependent yield of the above-threshold dissociation and the enhanced ionization of the molecule, we observed a few-femtosecond time delay in between the two dissociation pathways...

  4. 328. (G*) Wavelength-dependent depolarization in fiber-based supercontinuum
    Nicolas Couture (University of Ottawa)
    10/06/2021, 15:59
    Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

    Light possessing a broadband frequency spectrum, also known as a supercontinuum (SC), has facilitated a plethora of applications such as optical coherence tomography (OCT) and optical communication. In general, these spectra are produced by propagating narrow-band optical pulses through a highly nonlinear medium. Photonic crystal fibers (PCFs) are often used as the nonlinear medium for SC...

  5. 362. Multi-octave Parametric Amplification for Ultrashort Laser Pulses
    TJ Hammond (University of Windsor)
    10/06/2021, 16:03
    Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Oral (Non-Student) / Orale (non-étudiant(e))

    Optical parametric amplifiers deliver intense ultrashort pulses with broadly tuneable frequencies, useful for strong field physics, high harmonic generation, and attosecond experiments. Currently, this nonlinear amplification scheme relies on the second order nonlinearity, $\chi^{(2)}$,which is made possible only by crystals without centro-symmetry. More recently, investigations into a...

  6. 508. An exploration for new phenomena using high-harmonic generation in two-dimensional van der Waals materials
    Mr Chandler Bossaer (Joint Attosecond Science Laboratory, National Research Council and University of Ottawa)
    10/06/2021, 16:07
    Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)
    Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

    Attosecond science is a relatively new research field founded on high-harmonic generation (HHG) in atomic and molecular gases, which has recently transitioned to experiment in 3-dimensional solids. Most of the physics underlying attosecond pulse emission from 2-dimensional semiconductors is unknown. Following years of research focusing on HHG in bulk semiconductors, this project focuses on the...
