Detection of ozone by differential absorption using CO2 laser

  • K. Asai

The differential absorption method with the conventional CO2 laser is discussed for the detection and monitoring of ozone in ambient atmosphere. By using the P(14) line in the (00°1 to 02°0) and the R(16) line in the (00°1 to 10°0) band, the measurement of ozone was made in a field. As an experimental result, the minimum detectable concentration of 0.15 ppm was obtained with the system, and the concentration of 0.2 ppm was measured in a photo-chemical smog.
