A two-frequency differential absorption lidar is proposed in which the reference beam is formed from CO{sub 2} laser radiation and the radiation frequency of the working beam is tuned consequently to the lines of the NH{sub 3} 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 {approx} 1 ppm with an error of about 20%.
