Advanced Diagnostics and Analytic Tools for HF/DF Laser Technology

Physical Sciences Inc. (PSI) proposes to develop two sensitive diagnostics for HF chemical laser development:. a) a novel patented, multispectral imager; Adaptive Infrared Imaging Spectroradiometer (AIRIS) and b) Planar Laser Induced Fluorescence (PLIF).In Phase I we will design, assemble, characterize, and field test an AIRIS device to demonstrate its capability to provide a sensitive diagnostic for the spatial and spectral content of HF lasers and profiles of HF(v,J) concentration and gain. We alsopropose to develop a design for a PLIF instrument that would be delivered in Phase II. This device would be used by HF researchers to design and test advanced mixing nozzles for future HF lasers. These two diagnostic tools would provide developers ofhigh power chemical lasers with valuable data including spatial maps of populations of HF(v,J) levels, stability of HF output lines, and detailed maps of mixing.A successful Phase I and II program will result in two diagnostic devices that will be delivered to the Air Force. These tools will provide valuable design and verification data for development of the next generation of high power HF lasers. Follow onopportunities include diagnostics for ground based spaceborne lasers.
