In given article on the basis of the processing theory location a signal in an optical range efficiency heterodyne the laser system using single-mode a fiber-optical optical path is considered. It is shown that efficiency of transformation location signals at use of fiber-optical technology reaches 50 % (for comparison at a traditional method of mixture in free space efficiency of transformation makes 25%). Work of laser system as a part of information means of prompting and management of the weapon can be expressed as product of efficiency of transformation (a part of the signal collected by the reception aperture which actually falls on the detector) on efficiency heterodyne (the part of the accepted capacity falling on the detector which mixes up with a signal a heterodyne and promotes formation of a signal of intermediate frequency). Mixture is traditional weeding a heterodyne and the reflected signal occurs in free space. This method of mixture gives system effectiveness to 25% for the worst case diffuse to the purpose in a distant zone at insignificant cutting Gaussian field a heterodyne and a transferred signal. However now in modern laser systems application optical amalgamators on the basis of fiber optical paths even more often find. It is connected with their raised vibration resistance and reliability at operation. Therefore the problem of an estimation of efficiency laser heterodyne systems with fiber optical paths is actual. On the basis of the processing theory location a signal in heterodyne to the laser system using single-mode a fiber-optical optical path it is received about expression for an estimation of efficiency of transformation of the signal reflected from the purpose. From the parities presented in work follows that for the remote purposes from a constant specific an effective surface of dispersion efficiency of transformation depends only on the relation of a cut and practically does not depend on range
