With the intensive technological progress, the atmospheric monitoring has become one of the most important issues for the absolute majority of states in their environment protection activity.

The acquisition of on-line information about the state of the atmospheric layer is an integral part of both global and regional atmospheric monitoring.
LIDAR systems using laser radiation sources are often integrated into the systems of atmospheric monitoring.

The given two-laser system (one Ti:Sapphire lasers and one Nd:YAG laser) is designed for application in a mobile distant atmosphere monitoring complex as a radiation source. To determine chlorine, nitrogen dioxide or ozone in the atmosphere the differential method for detection of the second and third harmonics of Ti:Sapphire laser on the set wavelengths in the first channel of laser system is used. Radiation of the second harmonic of Nd:YAG laser in the second channel is used for probing of aerosol formations, and the third harmonic radiation is used as an auxiliary one at chlorine detection.
