The development of lasers capable of producing high-intensity pulses has opened a new area in the study of light-matter interactions. The corresponding laser fields are strong enough to compete with the Coulomb forces in controlling the dynamics of atomic systems and give rise to multiphoton processes. This book presents a unified account of this rapidly developing field of physics. The first part describes the fundamental phenomena occurring in intense laser-atom interactions and gives the basic theoretical framework to analyze them. The second part contains a detailed discussion of Floquet theory, the numerical integration of the wave equations and approximation methods for the low- and high-frequency regimes. In the third part, the main multiphoton processes are discussed: multiphoton ionization, high harmonic and attosecond pulse generation, and laser-assisted electron-atom collisions. Aimed at graduate students in atomic, molecular and optical physics, the book will also interest researchers working on laser interactions with matter.

'The book is a clear, up-to-date and self-contained presentation of the phenomena involved in the interaction of intense laser fields with atoms. It is recommended to students of postgraduate courses and researchers. It is also a basic literature to all who wish to have an insight [in]to this rather advanced field.'

'Atoms in Intense Laser Fields is a well-organized text … [it] is an excellent introduction to the phenomena and methods of strong-field, laser-atom physics … a solid exposition of the central discoveries and theoretical concepts that form the foundation of the field.'

'The descriptions given by Joachain and co-authors are always extremely clear and complete and therefore this book will certainly remain a masterpiece in the field for several years … very exciting results.'
