Abstract

The energy spectra of electrons emitted radially from a CO2 laser focus originating from the ionization of K and Xe atoms of tenuous gas pressure are measured. We simultaneously measured the cases in which medium laser intensities and high laser intensities are applied, fitting the ADK tunneling theory.
