abstract

  • A ’’vibrational-bath’’ model is employed to determine the characteristics of the absorption of pulsed CO2 laser radiation by SF6 at the 10.4-μm band of CO2. This model allows calculation of the absorption of any CO2 P line, other than that of the incident pulse, both during and after the pulse transmission and over a wide range of pulse intensities. Infrared double-resonance experiments, using both short and long pump pulses, demonstrate the appropriateness of the model in predicting the SF6 absorption behavior and the range of SF6 pressures and input pulse durations where such a model applies.
