On the basis of the use of the basic concepts and relations photometry in the single-scattering of radiation by inhomogeneities of the material of the active element, an analytical expression for the spectral power density of the active element of the scattered optical radiation of the pump lamps, reaching the input of the receiver at a range of intelligence, describing the spectral, energy and temporal characteristics of the radiation optical pumping system at the output of the laser resonator transmission channel means. For cases of three- and four-generation schemes established relationship between the density of the population inversion of the active element and the received power of the radiation emitted by the active element.
