Two-Color and Single-Color above Threshold Ionisation

  • Pierre Agostini
Chapter

Abstract

My aim for this first lecture is to give an account of some of current interest aspects of Above-Threshold Ionisation (ATI) and, more specifically, of two-color ATI of atoms which is in some sense much simpler than single-color ATI. In two-color ATI (Fig.1), one field (in the XUV —X-ray domain) is too weak to induce multiphoton processes but its photons are energetic enough to photoionize the atom. The other field, on the contrary (in the near IR) is relatively more intense and the probability for exchanging several photons with the atom is significant although it is too weak to ionize the atom by itself.
