Applied Physics Group
Welcome to the Applied Physics: Lasers and Optics Group Website.
Work in our group focuses on the use of lasers, electron beams, microwaves and magnetic devices to observe, control, accelerate, extract power and precondition gas flows for subsonic, supersonic and hypersonic fluid dynamics, for propulsion applications, and for high sensitivity gas detection related to homeland defense. Our research group is recognized for inventing a wide variety of new diagnostics including Planar Laser Induced Fluorescence (PLIF) for imaging of high speed flows, Angularly Resolved Coherent Raman Scattering (ARCS) for species measurement, Raman Excitation plus Laser Induced Electronic Fluorescence (RELIEF) for velocity imaging by molecular tagging in air, Photo Activated Nonintrusive Tracking of Molecular Motion (PHANTOMM) for velocity imaging by molecular tagging in water, Filtered Rayleigh Scattering (FRS) for imaging velocity, temperature, density and flow structure, Coherent Rayleigh Brillouin Scattering (CRBS) for point temperature measurements in gases and weakly ionized plasmas, Radar REMPI for point measurements of species, and the application of atomic and molecular filters for species and temperature imaging. Recently there has been much work on the development of plasma and MHD related flow control technologies and on the development of high power electron beam driven hypersonic ground test facilities for high Mach number testing. The group has strong collaborations with Boeing, Lockheed, Sandia National Labs, Air Force Research Labs, MSE Technology Applications, and numerous small companies through SBIR and STTR efforts.
