    Area of Science:

    • Laser Physics
    • Optical Engineering

    Background:

    • Coherent beam combining (CBC) is crucial for scaling laser power.
    • Phase locking of laser amplifiers is essential for effective CBC.

    Purpose of the Study:

    • To demonstrate active phase locking of slab laser amplifiers using a novel square wave dithering algorithm.
    • To experimentally validate the performance of this CBC technique.

    Main Methods:

    • Utilized a modulated- আরdithering technique (MPD) with dual-level square wave phase modulation.
    • Employed time division multiplexing and a single detector for phase error signal acquisition.
    • Implemented a closed-loop system for active phase control.

    Main Results:

    • Achieved stable coherent beam combining of two slab laser amplifiers, reaching 208 W output power.
    • Reported a high contrast of the combined beam profile (approximately 87%).
    • Demonstrated a combining efficiency of nearly 90.4%.

    Conclusions:

    • The square wave dithering algorithm enables effective active phase locking for slab laser amplifiers.
    • The demonstrated MPD technique offers a viable approach for high-power laser system integration.
    • Numerical simulations confirmed the feasibility of beam steering using this CBC method.
