Abstract:

THE PROPOSED STUDY WILL INVESTIGATE DAMAGE TO RV ANTENNA WINDOWS BY PULSED AND CW LASERS AT 0.35, 0.53, 1.6, AND 3.8 MICROMETERS. THE STUDY WILL CONSIST OF MEASURING THE TRANSMITTANCE, REFLECTANCE, ABSORPTION AND SCATTERING IN THE WINDOWS AT THE WAVELENGTHS OF INTEREST AND MEASURING THE SURFACE AND INDEPTH PHENOMENOLOGY (E.G. ABLATION SPALLING, EXFOLIATION, CRACKING) IN WINDOWS EXPOSED TO PULSED XEF, ND:GLASS AND CW, DF LASERS. THESE MEASUREMENTS WILL BE COUPLED TO THEORETICAL MODELS OF PULSED AND CW LASER INTERACTIONS WITH (THREE-DIMENSIONAL) FUSED SILICA TYPE MATERIALS TO ELUCIDATE DAMAGE MECHANISMS AND TO PERFORM THEORY/DATA COMPARISONS. THE COMPARISONS ARE EXPECTED TO SUGGEST IMPROVED METHODS OF HARDENING RV WINDOW MATERIALS TO LASER IRRADIATION. THE OBSERVED DAMAGE MECHANISMS WILL BE USED TO ESTIMATE PERFORMANCE DEGRADATION OF RV ANTENNAS, RV ANTENNA WINDOWS AND DEGRADATION IN CEP. A MAJOR MANUFACTURER AND INVENTOR OF RV ANTENNA WINDOW MATERIALS WILL BE A CONSUL-TANT TO THE PROPER AND SHALL ALSO SUPPLY THE PROPOSER WITH EXISTING STATE-OF-THE-ART WINDOW MATERIALS FOR TESTING AND ANALYSIS.
