The Springer Series on Atomic, Optical, and Plasma Physics covers in a
comprehensive manner theory and experiment in the entire field of atoms and
molecules and their interaction with electromagnetic radiation. Books in the series
provide a rich source of new ideas and techniques with wide applications in fields
such as chemistry, materials science, astrophysics, surface science, plasma
technology, advanced optics, aeronomy, and engineering. Laser physics is a
particular connecting theme that has provided much of the continuing impetus for
new developments in the field, such as quantum computation and Bose-Einstein
condensation. The purpose of the series is to cover the gap between standard
undergraduate textbooks and the research literature with emphasis on the
fundamental ideas, methods, techniques, and results in the field.
