Paper Abstract

A new system of the quantitatively analyzing spectroscopy by using a continuously scanning tunable dye laser is proposed. This system can detect simultaneously many components of pollutant gases by one scan. The maximum number of the detectable gas and the sensitivity of the detection is analyzed. The absorption spectrum is calibrated to the output of the laser and to the standard spectrum(Na) and the interpolating Fabry-Plrot interferometer. The gas concentration is calculated by the method of least squares. A foundamental experiment by using a rhodamine 6G dye laser is done. Three kinds of gases, NO2, I2 and Br2, are separately analyzed quantitatively.
