DTIC ADA144816: Investigation of the CARS Spectrum

More Book Details

Description of the Book:

Spectroscopic investigations were conducted into the coherent anti- Stokes Raman spectroscopy (CARS) spectrum of CO. CARS is a remote laser diagnostic technique for temperature and species measurements in hostile combustion environments. As such it possesses considerable relevance to the Air Force in the general areas of ballistics and propulsion. This final report describes the results of investigations conducted into the effects of high pressure, specifically the phenomenon of collisional narrowing, on CARS spectra from which temperature and density information derive. Experimental studies of CARS spectra were conducted in carbon monoxide in a heated, high pressure cell over the range 300K-1500K, 1-100 atm. The spectra were used to evaluate the UTRC CARS computer code supplied to RPL for the calculation of CO CARS frequency distributions
