The International Workshop on Laser Interactions and Related Plasma Phenomena is the oldest continuing series of meetings in the United States with published proceedings documenting much of the growth of this dynamic field. The meeting format is designed to provide an interactive atmosphere that encourages first disclosures along with in-depth critical reviews. The Eighth International Workshop was held at the Naval Postgraduate School at Monterey, California, 26-30 October 1986, under the continuing directorship of H. Hora (University of New South Wales) and G.H. Miley (University of Illinois). The local organizer was F. Schwirzke (Naval Postgraduate School).
