The Seventh International Conference on Laser Spectroscopy or SEICOLS'85 was held at the Maui Surf Hotel, Hawaii, USA, June 24 to 28, 1985. Like its predecessors at Vail, Megeve, Jackson Lake, Rottach-Egern, Jasper Park, and Interlaken, SEICOLS '85 aimed at providing an informal setting for active scientists to meet and discuss recent developments and applications in laser spectroscopy. The Conference site on the sunny sands of famed Kaanapali Beach on the Island of Maui, although perhaps not the traditional mountain resort, offered nonetheless an atmosphere most inspiring to creative discussions during the unscheduled afternoons. The Conference was truly international: 223 scientists represented 19 countries, including Australia, Canada, People's Republic of China, Denmark, Finland, France Germany (FRG), Great Britain, Israel, Italy, Japan, South Korea, Netherlands, New Zealand, Poland, Spain, Sweden, Switzerland, and U.S.A. The intense scientific program included 14 topical sessions with 59 invited talks. Approximately 60 additional invited papers and 16 postdeadline papers were presented during three lively evening poster sessions. The present Proceedings contain oral as well as poster and postdeadline papers. We thank all authors for the timely preparation of their manuscripts, now available to a wider audience. We would also like to thank the members of the International Steering Committee for their valuable suggestions and advice. Our special thanks go to the members of the Program Committee for their painstaking efforts.

In today's world, the range of technologies with the potential to threaten the security of U.S. military forces is extremely broad. These include developments in explosive materials, sensors, control systems, robotics, satellite systems, and computing power, to name just a few. Such technologies have not only enhanced the capabilities of U.S. military forces, but also offer enhanced offensive capabilities to potential adversaries - either directly through the development of more sophisticated weapons, or more indirectly through opportunities for interrupting the function of defensive U.S. military systems. Passive and active electro-optical (EO) sensing technologies are prime examples. Laser Radar considers the potential of active EO technologies to create surprise; i.e., systems that use a source of visible or infrared light to interrogate a target in combination with sensitive detectors and processors to analyze the returned light. The addition of an interrogating light source to the system adds rich new phenomenologies that enable new capabilities to be explored. This report evaluates the fundamental, physical limits to active EO sensor technologies with potential military utility; identifies key technologies that may help overcome the impediments within a 5-10 year timeframe; considers the pros and cons of implementing each existing or emerging technology; and evaluates the potential uses of active EO sensing technologies, including 3D mapping and multi-discriminate laser radar technologies.
