A new wavefront control approach for mitigation of atmospheric turbulence-induced wavefront phase aberrations in coherent fiber-array-based laser beam projection systems is introduced and analyzed. This approach is based on integration of wavefront sensing capabilities directly into the fiber-array transmitter aperture. In the coherent fiber array considered, we assume that each fiber collimator (subaperture) of the array is capable of precompensation of local (onsubaperture) wavefront phase tip and tilt aberrations using controllable rapid displacement of the tip of the delivery fiber at the collimating lens focal plane. In the technique proposed, this tip and tilt phase aberration control is based on maximization of the optical power received through the same fiber collimator using the stochastic parallel gradient descent (SPGD) technique. The coordinates of the fiber tip after the local tip and tilt aberrations are mitigated correspond to the coordinates of the focal-spot centroid of the optical wave backscattered off the target. Similar to a conventional Shack-Hartmann wavefront sensor, phase function over the entire fiber-array aperture can then be retrieved using the coordinates obtained. The piston phases that are required for coherent combining (phase locking) of the outgoing beams at the target plane can be further calculated from the reconstructed wavefront phase. Results of analysis and numerical simulations are presented. Performance of adaptive precompensation of phase aberrations in this laser beam projection system type is compared for various system configurations characterized by the number of fiber collimators and atmospheric turbulence conditions. The wavefront control concept presented can be effectively applied for long-range laser beam projection scenarios for which the time delay related with the double-pass laser beam propagation to the target and back is compared or even exceeds the characteristic time of the atmospheric turbulence change - scenarios when conventional target-in-the-loop phase-locking techniques fail.

Modern nonlinear and coherent optics provides a great variety of possibilities to create many types of spatially distributed neural network optical systems and uses them to simulate the collective behavior of dynamics systems with nonlocal interactions (e.g., analogs of advanced neural networks).' We can point out the following basic properties of these systems: — intrinsic N-shape nonlinearity (bistable or multistable optical response); — existence of the local excitation transfer mechanism (e.g., diffusion); — possible implementation of large scale (nonlocal) interactions; All these requirements can be fulfilled in nonlinear 2-D feedback optical systems: in various nonlinear resonators and interferometers.2 Complexity and variety of nonlinear dynamic modes (different selfoscillation and dissipative structures, optical turbulence) observed in neural network optical systems with the simplest nonlocal interconnectors promote the search for principal most important models of large scale interactions and corresponding nonlinear dynamic structures. One of these models is one-dimensional rotational instability occurring in a neural network system with rotated field.3 Rotating waves observed in this system have been analyzed in detail.4 Theoretical and experimental research of 2-D models of optical neural networks appears to be most interesting. Implementing any type of "pure" nonlocal interconnectors in an optical experiment is a rather complicated task. Optical aberrations and some other factors result in the fact that additional "spurious" interactions affecting dynamic structures being formed in the system seem to be superimposed on a given type of nonlocal interconnectors. The only possibility to examine multiple nonlinear structures corresponding to a certain type of large scale interactions appears to be a comparative analysis of optical and numerical experiments in which the interconnect topologies can be defined in a "pure" form. 2-D selfoscillation structures observed in a neural network with 2-D optical feedback and nonlocal interconnectors have been studied in this paper. The simplest types of topological transforms, i.e., lateral inversion and rotation, are realized in optical and numerical experiments.
