  • Transverse structure evolution was monitored.
  • Energy deposition into the medium was quantified.
  • The influence of laser beam quality on array formation was assessed.

    • Main Results:

    • The Dammann grating produced regular multifilament arrays.
    • The phase plate method showed higher sensitivity to laser beam quality.
    • The Dammann grating method demonstrated greater robustness in array formation.
    • Differences in energy deposition patterns were observed between the two methods.

    Conclusions:

    • Dammann gratings provide a more stable and reliable method for generating multifilament arrays compared to TEM11 phase plates.
    • The Dammann grating approach is less susceptible to variations in laser beam quality, making it advantageous for practical applications.
    • This finding has implications for optimizing laser processing and material modification techniques.
