The 1993 Gordon Research Conference on the Physics and Chemistry of laser Diagnostics in Combustion was held at Plymouth State College (South) in Plymouth, New Hampshire, July 12-16, 1993. This conference is primarily concerned with the fundamental physics and chemistry underlying the wide variety of laser-based optical spectroscopic diagnostic techniques which are used for studying combustion processes. The focus is on in-situ and nonperturbing optical methods for one-, two-, and three-dimensional measurements of species concentrations, temperature, and velocity. The development of such quantitative methods using linear and nonlinear optical interactions encompasses a broad scope of interdisciplinary research including basic and applied physics and chemistry.

The Gordon Research Conference (GRC) on LASER DIAGNOSTICS IN COMBUSTION was held at Mount Holyoke College from 7/31/2005 thru 8/5/2005. The Conference was well-attended with 121 participants (attendees list attached). The attendees represented the spectrum of endeavor in this field coming from academia, industry, and government laboratories, both U.S. and foreign scientists, senior researchers, young investigators, and students. In designing the formal speakers program, emphasis was placed on current unpublished research and discussion of the future target areas in this field. There was a conscious effort to stimulate lively discussion about the key issues in the field today. Time for formal presentations was limited in the interest of group discussions. In order that more scientists could communicate their most recent results, poster presentation time was scheduled. Attached is a copy of the formal schedule and speaker program and the poster program. In addition to these formal interactions, ''free time'' was scheduled to allow informal discussions. Such discussions are fostering new collaborations and joint efforts in the field. I want to personally thank you for your support of this Conference. As you know, in the interest of promoting the presentation of unpublished and frontier-breaking research, Gordon Research Conferences does not permit publication of meeting proceedings.
