Fundamentals of Laser Interactions II, Softcover reprint of the original 1st ed. 1989 Proceedings of the Fourth Meeting on Laser Phenomena Held at the Bundessportheim in Obergurgl, Austria, 26 February – 4 March 1989 Coll. Lecture Notes in Physics, Vol. 339

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.
