Strong field physics in a scaled interaction
Strong-field interactions at long wavelengths are studied experimentally and theoretically, and compared with studies at shorter wavelengths. Under similar dynamical conditions, we find a more pronounced role for atomic structure in the long wavelength studies. Ion core structure is reflected in photoelectron energy spectra in a manner consistent with the rescattering picture, and stronger coupling between ground and excited states influences high harmonic generation spectra. Spectral and temporal measurements of high harmonics generated from a mid-infrared fundamental are presented.
