    A new method effectively filters phase noise in pulsed laser coherent combination. This technique enables stable phase locking and ideal combined pulse intensity, advancing fiber laser systems.

    Area of Science:

    • Optics and Photonics
    • Laser Physics

    Background:

    • Multi-dithering is effective for continuous-wave laser phase locking.
    • Traditional filtering struggles with low repetition rate pulsed lasers due to frequency domain overlap between pulse signals and phase noise.

    Purpose of the Study:

    • To develop a novel method for detecting, identifying, and filtering phase noise in pulsed laser coherent combination.
    • To enable stable phase locking and high-quality coherent combination of low repetition rate pulsed lasers.

    Main Methods:

    • Proposed a novel method based on autocorrelation characteristics for pulse noise detection, identification, and filtering.
    • Developed a self-designed adaptive window filtering algorithm to remove pulse signals from phase noise.
    • Utilized the filtered phase noise signal as input for the multi-dithering method for phase locking.

    Main Results:

    • Successfully filtered pulse signals from phase noise within approximately 0.1 ms.
    • Achieved zero phase difference compensation for two pulsed beams (10 kHz) via closed-loop phase lock.
    • Realized stable phase locking with short correction periods and achieved an ideal combined pulse intensity of 0.9I0.

    Conclusions:

    • The proposed adaptive window filtering method effectively addresses phase noise challenges in pulsed laser coherent combination.
    • This technique facilitates stable phase locking and enhances the quality of combined laser pulses.
    • The method has potential applications in large array fiber laser systems and fiber phased array lidar.
