At this Obergurgl seminar, theoreticians and experimentalists discussed recent developments in laser interactions. This volume contains the texts of invited lectures and abstracts of contributed papers. The main topics discussed are: multiphoton ionization above-threshold ionization collisions in strong fields atoms in intense fields chaos in radiative interactions electron correlations in multiphoton processes Rydberg atoms in external fields other laser interactions. Thus a broad and up-to-date account of laser interactions is given which will be of interest to scientists, engineers and graduate students.
