Abstract : In August 1986, in Chengdu city, we did on-the- spot measurements of attenuation in the atmosphere associated with 40 spectral lines of CO2 laser radiation within oscillation bands 00 deg 1 - 10 deg 0 and 00 deg 1 - 02 deg 0. This article gives general values for various spectral line attenuation coefficients. In conjunction with this, it describes attenuation characteristics. Under the specific conditions of the Chengdu area in August, water vapor absorption and gas aerosol particle absorption along with scattering form the principal components of attenuation. Attenuation coefficients measured in association with various spectral lines can supply beneficial references for CO2 laser atmospheric applications.
