Absorption of ozone molecules in strong field of tea CO2 injection laser

The relationship between the IR radiation energy absorbed by ozone and the energy density was investigated at pressures at which collisions have a significant influence on the energy absorption mechanism but do not cause transitions between the oscillatory levels over time intervals equal to the light pulse duration. A radiation injection stabilized TEA CO2 laser was employed as the radiation source. The results obtained with and without injection were compared, indicating that the energy absorbed by the medium is proportional to the square root of the energy density for densities ranging from 0.001 to 320 J/square centimeters. Collision mode absorption of intense radiation is examined theoretically, showing qualitative agreement with the experimental findings.
