Selectivity improvement of air pollution detection by using optothermal laser spectroscopy
Optothermal CO2 laser spectroscopy of air polluted by CO2 and SO2 has been performed with improved selectivity in the low pressure range. The ability of kinetic cooling effects to give additional improvement of the detection selectivity is demonstrated.
