Abstract : During this first year, research has concentrated on the acquisition of laser systems and the construction of our test facility. We have achieved two major research milestones: the demonstration of velocity tagging, and the demonstration of the simultaneous measurement of two-dimensional temperature and pressure fields. We are currently studying the nonlinear effects associated with high intensity laser fields with a particular interest in how they affect the measurements of flow properties. Keywords: Flow diagnostics; Velocity measurements; Temperature measurements; Density measurements; Laser diagnostics; Supersonic flows; Turbulent three dimensional flow.
