    Main Methods:

    • Experimental setup utilizing a five-channel linear array of independent laser oscillators.
    • Operation in adaptive mode with real-time correction of atmospheric effects.
    • Propagation over a 1-km range with target plane measurements.

    Main Results:

    • Near diffraction-limited beam quality was achieved in the target plane.
    • Effective correction of atmospheric distortions was demonstrated.
    • The system exhibited scalability towards high power levels.

    Conclusions:

    • Phase-conjugation adaptive arrays driven by independent laser oscillators are effective for atmospheric compensation.
    • The demonstrated technology shows promise for high-power laser systems requiring precise beam control.
