Abstract. A method is proposed that involves adaptive change of laser power depending on the size of the forest area under study for early detection of forest fires. The proposed method is optimized in relation to finding such a power- distance dependence that minimizes the detectable concentration of the sought substance — the combustion product. Taking into account the limitation of the energy resource allocated for such monitoring, a functional dependence of the optimal power of the probing radiation on the distance to the object is obtained, at which the threshold for recording the concentration of combustion products reaches the lowest value.
