Strong Optical Field Ionization of Solids
… valence to conduction band in the presence of an intense laser field is explored theoretically in semiconductors and dielectrics. Experiments on intense laser driven dielectrics have revealed population transfer to the conduction band that differs from that seen in semiconductors. Our research …

Fundamental Studies And Applications Of Strong Field Ionization
<p>In an intense laser field, atoms and molecules experience tunneling ionization directly to the continuum. We used this method to study several aspects and applications of strong field ionization (SFI) in atoms and molecules. One study used SFI to probe the photofragments produced by …

High harmonic generation by short laser pulses: time-frequency behavior and applications to attophysics
… a process in which noble gas atoms excited by an intense laser field at frequency ω<sub>1</sub> emit radiation of higher frequencies that are odd integer multiples of ω<sub>1</sub>. Driven by an infrared laser, high harmonic radiation can span from the optical into the extreme ultraviolet (XUV) …
