Book Description
The generation of harmonics due to the nonlinear properties of a microwave plasma discharge is investigated theoretically and experimentally. The nonlinear effects of collisons, spatial variations of rf electric field and plasma density, and sheaths are analyzed. With the objective of developing an efficient harmonic generator and understanding the basic discharge mechanisms, various experimental techniques and configurations are explored. In order to obtain the harmonic current due to a velocity-dependent collision frequency, the veclocity distribution function is expanded in terms of spatial and time harmonics. By means of successive partial integrations along with the appropriate approximations, the third harmonic current for low collision frequencies is obtained in a particularly convenient form. It is shown that the effects of collisions constitute and inefficient method of harmonic generation and cannot account for the observed harmonics. (Author).

Book Description
This book represents the first comprehensive treatment of high-order harmonic generation in laser-produced plumes, covering the principles, past and present experimental status and important applications. It shows how this method of frequency conversion of laser radiation towards the extreme ultraviolet range matured over the course of multiple studies and demonstrated new approaches in the generation of strong coherent short-wavelength radiation for various applications. Significant discoveries and pioneering contributions of researchers in this field carried out in various laser scientific centers worldwide are included in this first attempt to describe the important findings in this area of nonlinear spectroscopy. High-Order Harmonic Generation in Laser Plasma Plumes is a self-contained and unified review of the most recent achievements in the field, such as the application of clusters (fullerenes, nanoparticles, nanotubes) for efficient harmonic generation of ultrashort laser pulses in cluster-containing plumes and resonance-induced enhancement of harmonic yield. It can be used as an advanced monograph for researchers and graduate students working in the field of nonlinear spectroscopy. It is also suitable for researchers in laser physics and nonlinear optics who wish to have an overview of the advanced achievements in laser ablation-induced high-order harmonic generation spectroscopy. The carefully presented details of this book will be of value to research devoted to the understanding and control frequency conversion of laser pulses in plasma plumes. The studies described in this book pave the way for the development of a new method of materials studies using the laser ablation-induced high-order harmonic generation spectroscopy, which can exploit the spectral and structural properties of various solid-state materials through their ablation and further propagation of short laser pulse through laser-produced plasma and generation of high-order harmonics.

Book Description
This book comprises a detailed consideration of novel approaches developed in the field of frequency conversion of laser sources in laser-induced plasmas during the last few years. The aim of the book is to support researchers and other readers in their development in the area of high-order nonlinear spectroscopy. Particularly, the advanced studies of nanoparticles and quantum dots for the formation of new sources of radiation in different short-wavelength spectral ranges show the ways to further implement the specific features of small-sized species in a relatively new field of study—laser ablation induced high-order harmonics generation spectroscopy. Researchers involved in the development of new methods of frequency conversion will benefit from finding the most recent advances in this field. Undergraduate students will discover interesting information about recent findings in plasma harmonic research. Additionally, the usefulness of the book will be demonstrated by the potential applications of the new knowledge developed during recent years for ultrafast pulse generation using the proposed schemes of plasma-light interaction. Thus, the audience may also include those researchers involved in state-of-the-art developments in attophysics. Additionally, any professionals interested in the application of the advanced techniques for material science will also benefit from updating their knowledge of new methods of material studies using high-order nonlinear spectroscopy.

Book Description
This 6th International Workshop in the series starting in 1969 was held at the Naval Postgraduate School in Monterey, California from 25-29 October, 1982 under the continuing directorship of Heinrich Hora. The co-directorship of the late Helmut Schwarz who helped found the series was assumed by George Miley. Fred Schwirzke served as the local organizer. Following a commemoration for Helmut Schwarz, Heinrich Hora connnented that the long title of the workshop is originally due to Nicholas Bloembergen, who prophetically envisaged that "related plasma phenomena" such as is involved in particle beam fusion is also of enormous interest to the laser connnunity. The en thusiastic response of the workshop advisors and the 82 participants from 11 countries supports the need for a continuation of this work shop-type meeting where an innnediate discussion and documentation of new results and conceptual formulations occurs, a process not possible through the usual journals. The main sponsor of this year's confer ence was the Fusion Studies Laboratory of the University of Illinois. Thanks are also due to the Naval Postgraduate School, Monterey, and the Department of Theoretical Physics, University of New South Wales. The conference was made feasible by the contributions of the partici pants, and they and their institutions deserve many thanks. Special recognition is due to the Conference Secretary, Chris Stalker (Urbana), as well as to Marie Wesson (Sydney) and to Patricia Vardaro (Monterey).

Book Description
Plasma harmonics is a new field of laser spectroscopy. The use of the solid elements of the periodic table, together with thousands of complex solid-state samples, largely extends the range of materials employed in plasma harmonics in contrast to the few light rare gases that are typically used. Thus the exploration of practically any available sol
