Abstract:
A two-frequency differential absorption lidar is proposed in which the reference beam is formed from CO2 laser radiation and the radiation frequency of the working beam is tuned consequently to the lines of the NH3 laser spectrum. It is shown that this lidar can be used to measure the concentration of freons and some other atmospheric pollutants as low as ~1 ppm with an error of about 20%.
