The aim of this NATO Advanced Study Institute was to bring together scientists and students working in the field of laser matter interactions in order to review and stimulate developmentoffundamental science with ultra-short pulse lasers. New techniques of pulse compression and colliding-pulse mode-locking have made possible the construction of lasers with pulse lengths in the femtosecond range. Such lasers are now in operation at several research laboratories in Europe and the United States. These laser facilities present a new and exciting research direction with both pure and applied science components. In this ASI the emphasis is on fundamental processes occurring in the interaction of short laser pulses with atoms, molecules, solids, and plasmas. In the case of laser-atom (molecule) interactions, high power lasers provide the first access to extreme high-intensity conditions above 10'8 Watts/em', a new frontier for nonlinear interaction of photons with atoms and molecules. New phenomena observed include multiphoton ionization processes, atomic collisions in the presence of a strong laser field, Coulomb explosion following rapid ionization of a molecule and the production of high harmonics of the laser source. Another important topic reviewed in this ASI is the lasercooling ofatoms.

Laser-Beam Interactions with Materials treats, from a physicist's point of view, the wide variety of processes that lasers can induce in materials. Physical phenomena ranging from optics to shock waves are discussed, as are applications in such diverse fields as semiconductor annealing, hole drilling and fusion plasma production. The approach taken emphasizes the fundamental ideas and their interrelations. The newcomer is given the necessary important background material, while the active research worker finds a critical and comprehensive review of the field.

Lasers, having proven useful in such diverse areas as high resolution spectroscopy and the guiding of ferryboats, are cur rently enjoying great popularity among materials scientists and engineers. As versatile sources of "pure" energy in a highly concentrated form, lasers have become attractive tools and re search instruments in metallurgy, semiconductor technology and engineering. This text treats, from a physicist's point of view, some of the processes that lasers can induce in materials. The field of laser-material interactions is inherently mul tidisciplinary. Upon impact of a laser beam on a material, electromagnetic energy is converted first into electronic exci tation and then into thermal, chemical and mechanical energy. In the whole process the molecular structure as well as the shape of the material are changed in various ways. Understand ing this sequence of events requires knowledge from several branches of physics. A unified presentation of the subject, for the benefit of the materials researcher as well as the advanced student, is attempted here. In order to keep the book reason ably trim, I have focused on laser effects in solids such as thin films and technological materials. Related topiCS not cov ered are laser-induced chemical reactions in gases and liquids and laser effects in organic or biological materials.
