Coherent anti-Stokes Raman scattering of molecular gases. Final report 1 Mar 75--30 Apr 77

Technical Report ·
OSTI ID:6672902
An experimental system based upon a single-mode ruby laser and a ruby-pumped dye laser has been developed to investigate coherent anti-Stokes Raman scattering (CARS) of molecular gases. The CARS system is capable of both broad- and narrow-band operation. Theoretical and experimental results obtained using this system for such gases as H/sub 2/, HF, CO, N/sub 2/, and CH/sub 4/ are given. In particular, real-time CARS spectra of these gases have been obtained for rotational temperature estimations, and the pressure dependence of integrated CARS intensity has been determined. In addition, the effect of media turbulence upon laser-beam propagation and upon the CARS process has been investigated. Results of CARS measurements on a laboratory rocket-engine plume are also presented.
