    Area of Science:

    • Photonics
    • Materials Science
    • Optical Engineering

    Background:

    • Acousto-optic deflectors (AODs) are crucial for laser beam scanning in microprocessing.
    • Conventional AODs use 1D refractive index modulation, limiting performance.
    • Phased array transducers can improve resolution and performance by tilting modulation planes.

    Purpose of the Study:

    • To investigate dynamic two-dimensional (2D) acousto-optic deflection using ultrasonic beam steering.
    • To numerically simulate strain-induced index modulation via the photoelastic effect.
    • To analyze the impact of various parameters on 2D AOD performance.

    Main Methods:

    • Utilized an ultrasonic beam steering approach.
    • Numerically simulated 2D strain-induced index modulation.
    • Investigated parameters including radiofrequency, beam steering angle, and transducer pressure distributions.

    Main Results:

    • Demonstrated the feasibility of dynamic 2D index modulation in acousto-optic deflectors.
    • Showcased the influence of operating parameters on deflection characteristics.
    • Highlighted the potential for enhanced performance metrics like deflection angle and diffraction efficiency.

    Conclusions:

    • Dynamic 2D acousto-optic deflectors offer superior performance over conventional devices.
    • Ultrasonic beam steering provides a versatile method for controlling 2D modulation.
    • This approach paves the way for next-generation laser microprocessing systems.
