CO2 laser absorption in sf 6-air boundary layers - NASA/ADS

The injection of gaseous Sulfr hexafluoride into aircraft and missile boundary layers can attenuate the 10.6-micron radiation typical of CO2 laser beams. This absorption of laser radiation diminishes with increasing temperature, however. The INJECT boundary layer code has been modified in an effort to predict CO2 laser absorption by Sulfr hexafluoride in planar, turbulent boundary layers. The absorbed energy is found toGet price
