Characterizing multielectron dynamics during recollision
Graham G. Brown, Dong Hyuk Ko, Chunmei Zhang +1
Measuring the delay for an electron to emerge from different states is one of the major achievements of attosecond science. This delay can have two origins - the electron wave pack…
Near-field imaging of dipole emission modulated by an optical grating
Dong Hyuk Ko, Graham G. Brown, Chunmei Zhang +1
Multiphoton-ionized electrons are born into a strong light field that will determine their short-term future. By controlling the infrared beam, we enable atoms or molecules to gene…
Characterizing Fano Resonances During Recollision
Graham G. Brown, Dong Hyuk Ko, Chunmei Zhang +1
When intense light irradiates a quantum system, an ionizing electron recollides with its parent ion within the same light cycle and, during that very brief (few femtosecond) encoun…
Control of Air Lasing
Mathew Britton, Marianna Lytova, Dong Hyuk Ko +6
A near-infrared laser generates gain on transitions between the and states of the nitrog…
Femtosecond-laser-induced nanoscale blisters in polyimide thin films through nonlinear absorption
A. T. K. Godfrey, L. N. D. Kallepalli, J. J. Ratté +2
Nonlinear absorption of femtosecond laser pulses provides a unique opportunity to confine energy deposition in any medium to a region that is below the focal diameter of a pulse. I…
