Fluorine-atom probe techniques for chemical lasers

Abstract

The infrared absorption coefficient and Raman scattering cross sections of the fluorine-atom 2P3/2→2P1/2 transition at 404 cm−1 are estimated. The results are discussed in terms of probing fluorine-atom concentrations in chemical lasers. It is shown that absorption and coherent anti-Stokes Raman scattering can give sensitivity better than 1015 atoms/cm3.
