Remote detection of chem/bio hazards via coherent anti-Stokes Raman spectroscopy

Abstract

The goal the project is to assess the feasibility of Femtosecond Adaptive Spectroscopic Technique applied to coherent anti-Stokes Raman spectroscopy (FAST CARS) for a real time remote detection of hazardous microparticles in atmosphere and to evaluate the range of distances for typical species and the parameters of laser system that drive the limits of applicability. We will formulate a semiclassical theory of nonlinear scattering to estimate the number of detectable photons from a prototype molecule at a distance.
