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 sessionswith 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.

Autorentext
Yuen Ron Shen received his BS degree from the National Taiwan University in 1956 and his Ph.D. from Harvard University in 1963 under the supervision of Nicolaas Bloembergen. After a year of postdoctoral work at Harvard, he was appointed to the Physics faculty of the University of California at Berkeley where he has been ever since. He has also been associated with the Lawrence Berkeley National Laboratory since 1966. Shen's research interest is in the broad area of interaction of light with matter. He was involved in the early development of nonlinear optics, searching for basic understanding of various nonlinear optical phenomena. He is the author of the widely used text "The Principles of Nonlinear Optics". He contributed to the early accurate determination of band structures of semiconductors by developing a high-resolution wavelength-modulation spectroscopic technique. He initiated the field of nonlinear optics in liquid crystals and applications of nonlinear optics to characterization of liquid crystals. He pioneered the development of optical second harmonic generation and sum-frequency generation as powerful spectroscopic tools for surface and interface studies and their applications to many neglected, but important, areas of surface science. More recently, he has devoted himself to the development of sum-frequency generation as a novel sensitive probe for molecular chirality. Shen has received numerous prestigious awards including the 1986 Charles H. Townes Award of the OSA, the 1992 Arthur L. Schawlow Prize and the 1998 Frank Isakson Prize of the APS, and the 1996 Max-Planck Research Award. He is a member of the American Academy of Arts and Sciences, the National Academy of Sciences, and the Academia Sinica. He is also a foreign member of the Chinese Academy of Sciences.
