Linear conjugate phase-locking of independent single-mode emitters

The problems of the construction of laser systems based on the methods of linear adaptive optics and designed for energy transport over large distances in outer space are analysed. New approaches are proposed to the organisation of the linear phase conjugation of output and beacon-signal radiations. For definite ratios of the beacon-signal (ω_b), heterodyne (ω_h), and power (ω_p) radiations (ω_b > ω_h > ω_p or ω_b < ω_h < ω_p), the phase conjugation loop may play simultaneously the role of a precision frequency matching loop. This feature permits the phase locking of independent single-mode laser emitters, including phase locking in the far-field zone, to achieve the modular principle of system design and to generate the wavefront of radiation with a large cross section.
