    Area of Science:

    • Optics and Photonics
    • Quantum Optics

    Background:

    • Diffraction is a fundamental wave phenomenon.
    • Understanding the diffraction of ultrashort light pulses is crucial for advanced optical applications.
    • Existing models often assume long pulses (many cycles), limiting their applicability to few-cycle scenarios.

    Purpose of the Study:

    • To develop a theoretical framework for analyzing the diffraction of few-cycle light pulses.
    • To accurately model the behavior of ultrashort pulses in diffractive environments.
    • To provide a method that reproduces known phenomena in ultrashort pulse diffraction.

    Main Methods:

    • A perturbative technique is employed to solve the diffraction problem.
    • The propagated field is represented as a series of correction terms.
    • The solution builds upon diffraction laws established for many-cycle pulses.

    Main Results:

    • The perturbative approach successfully addresses the diffraction of few-cycle light pulses.
    • First- and second-order correction terms are sufficient to capture key features.
    • The derived model reproduces previously reported characteristics of ultrashort pulse diffraction.

    Conclusions:

    • The perturbative technique offers an effective solution for few-cycle light pulse diffraction.
    • The findings validate the applicability of the method for understanding complex light-matter interactions with ultrashort pulses.
    • This work advances the theoretical understanding of light pulse propagation and diffraction.
