B -- STUDY OF ADVANCED LASER TECHNIQUES, NONLINEAR OPTICS, SURFACE PROCESSES, AND RELATED AREAS SOL 52SBNB5C8795 DUE 090795 POC Debra A. Hoffman (301) 975-4648/Pauline Mallgrave (301) 975-6330 This synopsis is to modify the previously published description of the subject solicitation. The National Institute of Standards and Technology (NIST) intends to contract for research services and technical reports in the study of advanced laser techniques, non-linear optics, surface processes and related areas. The Contractor shall provides services consisting of (1) infrared (vibrationally resonant) non-linear optical sum frequency (SFG) spectral and dynamical studies of molecules at interfaces, (2) design, alignment, and characterization of a tunable femtosecond laser apparatus capable of doing SFG spectral and dynamical studies of electronic states localized at semiconductor interfaces, (3) characterization of detection systems (eg. CCD arrays) needed to detect the SFG signal, (4) demonstration of prototype spectral and dynamic measurements and performance of subsequent measurements of SFG, and (5) preparation of monthly reports on the project ''Femtosecond Laser Non-linear Optical Studies of Interfaces.'' The Government anticipates award of a firm-fixed-price contract with period of performance commencing August 31, 1995 through August 31, 1996 and an option for an additional year. All responsible sources may submit a proposal which shall be considered by the agency. Please request copies of the solicitation in writing to fax number (301) 963-7732. (0199)
