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).

Description

The 7th International Workshop in the series LASER INTERACTION AND RELATED PLASMA PHENOMENA continued the high standards established by the earlier meetings in this series. It was organized under the directorship of Heinrich Hora and George H. Miley at the Naval Postgraduate School in Monterey, California, with Fred Schwirzke as the local organizer. These workshops have presented many "firsts" in laser plasma interactions and especially in laser fusion. Some presentations provided continuity with the past, most represented advancements; however, in some workshops, progress did not appear to be occurring as rapidly as in others. Therefore, it was a special pleasure that in the present workshop when, on October 30, 1985, Chiyoe Yamanaka disclosed a breakthrough in the generation of fusion neutrons with laser fusion targets. The 7th Workshop also continued to represent other new fields of laser-plasma interaction. The progress reported was most pronounced in the fields of X-ray lasers, laser acceleration of particles by electrostatic double layers in plasmas, and a particle beam technique to solve the geometric problem of muon-catalyzed fusion. The development of laser-plasma interactions at medium to high laser intensities may be seen in its whole complexity from a brief review of prior conferences. At the first Workshop in 1969, a comprehensive review of the field was presented by the speakers with the opening address by N.

Description

The 9th International Workshop on "Laser Interaction and Related Plasma Phenomena" was held November 6-10, 1989, at the Naval Postgraduate School, Monterey, Cal ifornia. Starting in 1969, thi s represents a continuation of the longest series of meetings in this field in the United States. It is, in fact, the longest series anywhere with published Proceedings that document the advances and the growth of this dynamic field of physics and technology. Following the discovery of the laser in 1960, the study of processes involved in laser beam interactions with materials opened a basically new dimension of physics. The energy densities and intensities generated are many orders of magnitude beyond those previously observed in laboratories. Simultaneously, the temporal dynamics of this interaction covers a broad range, only recently reaching ultra short times, of the order of a few femtoseconds. Applications of this technology are of interest for many types of material treatments. Further, from the very beginning, a key ambitious goal has been to produce fusion energy by intense laser irradiation of a target containi ng appropriate fusion fuels. The vari ous phenomena discovered during the ensuing research on laser-fusion are, indeed, much more complex than originally expected. However, in view of recent advances in physics understanding, a route to successful laser fusion can be seen. The development of fusion energy received a very strong stimulation since the last workshop due to the now partially publicized results of underground nuclear explosions.
