    Area of Science:

    • Laser-induced terahertz (THz) radiation generation
    • Nonlinear optics and plasma physics

    Background:

    • Femtosecond laser pulses interacting with gases can generate THz radiation.
    • The polarization state of the laser pulse is a critical parameter influencing this process.

    Purpose of the Study:

    • To investigate how the polarization of multi-color femtosecond laser pulses influences the THz radiation emitted from ionized gases.
    • To determine the optimal polarization for maximizing THz energy yield based on the number of laser harmonics used.

    Main Methods:

    • Theoretical modeling using a local-current model and plane wave evaluations.
    • Comprehensive 3D numerical simulations of gas jet experiments.
    • Analysis of THz energy yields and polarization states.

    Main Results:

    • A crossover in THz energy yields was predicted and confirmed, where circular polarization is more efficient for fewer laser harmonics, and linear polarization becomes favorable for more than six harmonics.
    • This polarization-dependent efficiency was observed in both singly and multiply ionized gases.
    • Rotation of the THz polarization ellipse under circular laser polarization was attributed to phase shifts altering harmonic phase angles.

    Conclusions:

    • The polarization state of multi-color femtosecond laser pulses plays a crucial role in optimizing THz radiation generation.
    • Understanding this polarization dependence allows for tailored laser-gas interactions to control THz output.
    • The findings provide insights into controlling THz emission through laser polarization manipulation.
