abstract

  • Measurements were performed to determine the dynamical characteristics of high pressure SF6 absorption at the 10.4 μm band of CO2 as a function of laser pulse intensity. Both long (~ 200 ns FWHM) and short (~ 5 ns FWHM) CO2 laser pulses were employed. The observed pulse transmission characteristics can be accounted for using a vibrational bath model, which allows for the very large number of levels in the absorption spectrum of SF6.
