Ion Time-of-Flight and Vacuum Ultra-Violet Fluorescence Spectroscopy of Highly Ionized Nitrogen

Ryan Coffee
Graduate Student
UConn Physics Department

We investigate the dissociative ionization of diatomic molecules in ultra-fast laser fields. Following our discussion of a model for enhanced multi-photon excitation, we present a study of the vacuum ultra-violet fluorescence produced by molecules in strong laser fields. The results will show that not only is enhanced-excitation exclusive to molecules, but also that the excitation is highly selective. We will conclude with a multi-color pump-probe study that shows numerous wavelength dependence effects that will shake our traditional notions of dissociative ionization.
