Abstract
The refractivity of the CO2 gas is measured with an experimental error of 2% in the 10-μm region, using 10.4-μm band CO2 laser line. The frequency of the CO2 laser is swept through the Doppler profile of the laser line. The experiment is achieved using a 0.63-μm He−Ne/10.6-μm CO2-laser interferometer with a 2-m long vacuum cell. From the result, it is found that the Koch's formula also holds for the wavelengths in the 10-μm region within an accuracy of 2%.
