Energy Scaling of Gas Nonlinear Optics Invited
10:30-11:00
2017-10-04 10:30 2017-10-04 11:00 America/Denver Energy Scaling of Gas Nonlinear Optics Nonlinear light-matter interactions, such as filamentation or high-order harmonic generation, are at the heart of nonlinear optics. Scaling of such effects is crucial to benefit optimally from novel laser developments. We introduce and discuss a general scaling model for nonlinear light-matter interactions in gases.

Sub-Angstrom and Femtosecond Scale Imaging of Molecular Motion using Ultrafast X-ray Scattering Invited
11:00-11:30
2017-10-04 11:00 2017-10-04 11:30 America/Denver Sub-Angstrom and Femtosecond Scale Imaging of Molecular Motion using Ultrafast X-ray Scattering Time-resolved femtosecond x-ray diffraction patterns from laser-excited molecular iodine were used to create high fidelity molecular movies de-novo. We use a Legendre decomposition to extract excited state motion and observed electronic population transfer, vibrational motion, dissociation, rotational dephasing and evidence of interference of electronic states.
