Book excerpt: We describe experimental studies of resonantly enhanced multiphoton ionization (MPI) of cesium atoms in the presence and absence of an external electric field. In the zero-field studies, photoelectron angular distributions for one- and two-photon resonantly enhanced MPI are compared with the theory of Tang and Lambropoulos. Deviations of experiment from theory are attributed to hyperfine coupling effects in the resonant intermediate state. The agreement between theory and experiment is excellent. In the absence of an external electric field, signal due to two-photon resonant three-photon ionization of cesium via np states is undetectable. Application of an electric field mixes nearby nd and ns levels, thereby inducing excitation and subsequent ionization. Signal due to two-photon excitation of ns levels in field-free experiments is weak due to their small photoionization cross section. An electric field mixes nearby np levels which again allows detectable photoionization signal. For both ns and np states the field induced MPI signal increases as the square of the electric field for a given principal quantum number and increases rapidly with n for a given field strength. Finally, we note that the classical two-photon field-ionization threshold is lower for the case in which the laser polarization and the electric field are parallel than it is when they are perpendicular. 22 references, 11 figures.

Available in PDF, EPUB and Kindle. Book excerpt: Two- and three-photon ionization processes in cesium atoms using a single pulsed-dye laser and a cesium atomic beam have been investigated. Photoelectron angular distributions have been measured for two-photon resonant, three-photon ionization via the nd states (n = 12, 15, and 21), for two-photon nonresonant transitions over the photoelectron energy range from approx. 26 to 100 MeV, and for quasi-free-free transitions. 13 references, 6 figures.

Available in PDF, EPUB and Kindle. Book excerpt: The chapters of this volume represent the invited papers delivered at the 3rd International Conference on Multiphoton Processes (ICOMP III) held in Iraklion, Crete, Greece, September 5-11, 1984. The invited papers at a conference like ICOMP cannot possibly cover the whole field which has grown to immense proportions in recent years, overlapping with such diverse areas as atomic and molecular spectroscopy, plasma physics, nonlinear optics, quantum optics, etc. We believe these contributions represent that part of the research activity which has been attracting the most interest in the past year or so, as well as reviews of some of the more established topics. Even within this scope, and given the confines imposed by the fi nite duration of a conference, important and timely topics are inevitably left out. But then, there will be ICOMP IV. The collection of articles in this volume, combined with extensive ref erences to related work given by the authors, should provide an introduc tion to the major problems of the field and its state of the art. The chapters have been arranged according to thematic proximity, beginning with atoms, and continuing on with molecules and surfaces. This classi fication, however, would not cover all the subject matter even within the limited scope of the conference and of this volume.

Download or read book Multiphoton lonization of Atoms written by S.L. Chin and published by Elsevier. This book was released on 2012-12-02 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiphoton lonization of Atoms provides a pedagogical review of the whole subfield of multiphoton ionization of atoms. This book discusses the “normal multiphoton ionization of atoms; calculation of resonant multiphoton processes; and angular distribution of photoelectrons and light polarization effects in multiphoton ionization of atoms. The multiphoton ionization involving continuum-continuum transitions; creation of doubly charged strontium ions; and many-electron processes in nonlinear ionization of atoms are also elaborated. Other topics include the non-resonant multiphoton ionization of atoms; above-threshold ionization theory; autoionizing states in multiphoton transitions; and specific features of the spectra of alkaline-earth atoms. This publication is beneficial to physics students and researchers conducting work on the multiple ionization of atoms.

This book was released on 2022-02-25 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Laser stimulated scattering and multiphoton excitation is the first book to comprehensively cover laser stimulated scattering studies and laser multiphoton excitation-related studies. It is essential reading for academics, research scientists, and students working or interested in the areas of nonlinear optics, nonlinear photonics, laser spectroscopy, physical optics, physical chemistry, and optoelectronic engineering. Featuring cutting-edge discussions of new discoveries in the field, including stimulated Rayleigh-Bragg scattering (SRBS) and stimulated Mie scattering (SMS), the book also examines multiphoton excitation-based nonlinear optical effects, photoelectric effects, atomic and molecular ionizatoin effects, and molecular dissociation effects. Each major stimulated scattering effect is presented in its own chapter, alongside a description of the key concepts and mechanisms, as well as the necessary theoretical formulations. Furthermore, this is an engaging text that explains the latest experimental research achievements and their scientific and technological applications."--Back cover

This book was released on 2012-12-06 with total page 783 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Proceedings of the Advanced study Institute on Fundamental Processes in Atomic Collision Physics (Santa Flavia, Italy, September 10-21, 1984) are dedicated to the memory of Sir Harrie r-1assey, whose scientific achievements and life are reviewed herein by Sir David Bates. At the first School on the above topic (Maratea, September 1983, Volume 103 in this series), Harrie Massey presented the introductory lectures, summarized the entire lecture program, and presented an outlook on future developments in atomic collision physics. In an after-dinner speech, Massey recalled personal reminiscences and historical events with regard to atomic collision physics, to which he had contributed by initiating pioneering work and by stimulating and surveying this branch of physics over a period of almost six decades. Participants in the Maratea School will always remember Harrie Massey as a charming and wonderful person who was most pleased to discuss with everyone--students, postdoctorals, and senior scientists--any topic in atomic collision physics. Harrie Massey was a member of the Scientific Advisory Committee of the 1984 Santa Flavia School. Before his death he expressed his interest in attending this second School devoted to the presentation of recent developments and highlights in atomic collision physics. It is the desire of all authors to honor Harrie Massey with their contributions in these Proceedings.

Available in PDF, EPUB and Kindle. Book excerpt: In view of the rapid growth in both experimental and theoretical studies of multi-photon processes and multi-photon spectroscopy of atoms, ions and molecules in chemistry, physics, biology, materials science, etc., it is desirable to publish an advanced series of volumes containing review papers that can be read not only by active researchers in these areas, but also by those who are not experts but who intend to enter the field. The present series aims to serve this purpose. Each review article is written in a self-contained manner by the expert(s) in the area, so that the reader can grasp the knowledge without too much preparation.
