Abstract
The interactions of superstrong and ultrashort laser pulses with atoms and molecules have been a subject of great interest over the past two decades, as reflected in many books and review articles. The beginning of the twenty-first century is witnessing the development of several large- and medium-scale experimental facilities dedicated to the generation of laser light with unprecedented capabilities. The frequency spectrum covered by these new light sources ranges from the infrared up to the extreme ultraviolet and soft x-ray (produced in the FLASH free-electron laser facility at DESY). This calls for the development of new theoretical and computational tools to simulate laser-matter interactions at extreme conditions.

Notes
- 1.
This chapter is an updated version of Ullrich and Bandrauk (2006c) with many additional references and new examples in the area of direct double ionization of helium and molecular strong-field processes.

Strictly speaking, ATI belongs to the general class of multiphoton ionization phenomena. However, in practice it is understood that “multiphoton ionization” refers to the counting of various ionized states of atoms or molecules produced by the laser field, whereas ATI specifically refers to the photoelectron spectra.
