Abstract

The absorption of laser radiation on various atmospheric paths have been estimated basing on the data on spectral composition of HF, DF, and iodine lasers radiation and on the atmospheric molecular absorption coefficient. Applications of these lasers to atmospheric transmission problems require the information on the attenuation characteristics of the atmosphere at each of the lasing frequencies. Calculations have been made of the monochromatic transmission of HF and DF laser radiation for nonhomogeneous atmospheric slant paths. Aerosol extinction, continuum molecular absorption, and line absorption are included in the computations. An approximate Voigt profile has been used to express mixed Doppler-Lorentz line broadening. HF P₂(8) and DF P₂(8) lines are chosen among the presently operational cw chemical lasers for detailed studies.
