“…Relatively modest increases in puImping energy or efficiency would reduce the target length needed to reach saturation and thus lead to significant increases in output energy. We used a plain stainless steel target .or convenience, but there is evidence that a gold plasma would result in higher gains [8,16]; for example, Ref.…”

Paperwork teduction ABSTRACT (Maximum 200 words)The focus of this program is the development of extreme ultraviolet (XUV) lasers and their application to scientific problems. Laser development concentrates on the laboratory-scale lasers near 100 nm. The current application area is the development of very high resolution, microscopic imaging techniques. Such techniques should have a number of applications and be particularly useful in the life sciences. This report presents recent progress on XUV laser development. DTIC IntroductionThis program supported two related types of activities because there was a change of Principal Investigator (PI) during the period. The work of the original PI, Dr. P. J. K. Wisoff, concentrated on the development of short-pulse, blue-green dye laser systems, and their amplification to terawatt levels in a XeF(C --. A) electron-beam pumped, excimer amplifier system. This research, initiated under an earlier AFOSR grant, was very successful and of significant interest to the scientific community, as indicated by the list of publications and presentations in Section XX. Early in the first year of the grant period, Dr. Wisoff left Rice University to join the NASA Astronaut program. Dr. J. F. Young joined the Rice faculty at that time and took over direction of the program. In collaboration with Dr. Wisoff, he continued the existing projects to natural and productive conclusions, while initiating a new, but related, program focused on the development of extreme ultraviolet (XUV) lasers and their application to scientific problems. Laser development concentrated on the laboratory-scale Xe and H 2 lasers near 100 nm. The current application area is the development of very high resolution, microscopic imaging techniques. Such techniques should have a number of applications, and be particularly useful in the life sciences. This report reviews both areas of activities.

Program Highlights"* The dispersion of optical fibers around 500 nm was measured, and the data used to construct a fiber-prism pulse compressor. This was the first use of this technique in the blue-green spectral region."• A two-stage dye amplifier for blue-green, subpicosecond pulses was designed to supply injection pulses to the XeF(C --+ A) excimer amplifier."* The gain, energy output, saturation, and beam profile of the e-beam excited XeF(C --A) excimer amplifier was measured for various injection pulse lengths.
