Role of the intensity (duration) of excitation pulses in multiphoton infrared absorption and dissociation of SF₆ molecules

V. M. Apatin, G. N. Makarov


Abstract: The dependence of multiphoton infrared absorption by SF₆ molecules, cooled in a supersonic pulsed jet, was investigated in the collisionless excitation regime in the range of energy densities from 0.1 to 10 J/cm². A study was also made of the dependence of the yield resulting from dissociation of SF₆ molecules at T=300 K on the intensity (duration) of exciting CO₂ laser pulses. The dependences of the ratios of the absorbed energy to the dissociation yield on the excitation radiation frequency were obtained for different pulse intensities.
