Fragmentation dynamics of noble gas dimers in two-color intense laser fields
Abstract
We studied the dissociation dynamics of noble gas dimer ions in two-color infrared intense laser fields by analyzing their fragment-kinetic-energy-release spectra as a function of the pump-probe delay. Our calculations predict a striking ``delay gap'' in the kinetic-energy-spectra for all noble gas dimers that was so far only measured for the Ar2 dimer. We identify this phenomenon as a frustrated dissociation mechanism. This mechanism requests different pump- and probe-pulse wavelengths and involves the pump pulse to both, singly ionize the neutral dimers and dipole-couple adiabatic states in the dimer ion.
