    Area of Science:

    • Optics and Photonics
    • Fiber Lasers and Amplifiers

    Background:

    • Double-clad fibers are crucial for high-power fiber amplifiers.
    • Efficient pump-power absorption is key to amplifier performance.
    • Noncylindrical, chaotic cladding can enhance light propagation and absorption.

    Purpose of the Study:

    • To investigate the optimal design of double-clad fibers for improved pump-power absorption.
    • To develop a theoretical model for pump absorption in fibers with chaotic cladding.
    • To validate the theoretical model using numerical simulations.

    Main Methods:

    • Theoretical modeling based on the chaotic dynamics of rays within the fiber.
    • Numerical simulations using an adapted beam-propagation scheme.
    • Analysis of pump-absorption ratio in double-clad fibers with specific cladding geometries.

    Main Results:

    • Double-clad fibers featuring a doped single-mode core and noncylindrical multimode chaotic cladding demonstrate superior pump-power absorption.
    • A quantitative theory accurately predicts the pump-absorption ratio based on chaotic ray dynamics.
    • Numerical results favorably agree with the predictions of the developed theory.

    Conclusions:

    • Chaotic cladding in double-clad fibers is an effective strategy for optimizing pump-power absorption in amplifiers.
    • The proposed quantitative theory provides a valuable tool for designing and analyzing high-performance fiber amplifiers.
    • This work advances the understanding and application of chaotic dynamics in optical fiber technology.
