    A novel master-slave oscillator array offers efficient power extraction and high beam quality for large multiline lasers. This system enables advanced optical control, including beam steering and focusing, using phase-locked slave oscillators.

    Area of Science:

    • Laser Physics
    • Optical Engineering

    Background:

    • Large multiline lasers face challenges in efficient power extraction and maintaining beam quality.
    • Coherent optical adaptive techniques and precise beam control are crucial for advanced laser applications.

    Purpose of the Study:

    • To introduce a new system concept: a master and slave oscillator array for very large multiline lasers.
    • To address the optical challenges of efficient power extraction and good beam quality in such lasers.
    • To enable coherent optical adaptive techniques and fast electric steering and focusing.

    Main Methods:

    • A master oscillator synchronizes multiple slave oscillators through phase-locking.
    • Output beams from slave oscillators are coherently recombined, similar to a radar phase array.
    • Beam steering and focusing are achieved by dynamically controlling the phase of each slave oscillator.
