This paper is concerned with the phenomenon of the intermittence of structural states of laser beams-quasiperiodic discontinuous transitions between two structural states of the beam (a dislocationless and a stochastic state). The authors have studied the conditions of appearance and the specific features of manifestation of structural intermittence on near-the-ground slant and horizontal paths. The relationship between the optical effects studied and the changes of the turbulent properties of the atmosphere are discussed.
