Paper Abstract

Optical diagnostics in the area of high pressure propellant combustion require techniques which are effective in a highly turbulent, luminous, and sooting environments. Broadband, folded Coherent Anti-Stokes Raman Spectroscopy (CARS) shows particular promise in addressing these problem areas. The coherence and high intensity of the pulsed CARS signal make spatial and temporal rejection of interfering light possible. Sample volumes can be small and well defined when non-colinear beam geometrics are used. With pulsed and broad band lasers, the temperature and concentration of a flame species can be measured in a single shot, thus making the CARS technique suitable for the measurement of rapidly changing phenomena. This report describes our experimental setup for CARS measusrements and the progress we have made thus far in the application of CARS to double-base rocket propellant flames.
