    Main Results:

    • Significant differences in growth rates and up to 144% depth inhomogeneity observed between NCPs and PCPs.
    • NCPs excite higher peak carrier densities, leading to more efficient SPP generation.
    • Temporal chirp directly influences ionization rates due to distinct incident spectrum sequences.

    Conclusions:

    • Temporal chirp modulation is a viable method to control carrier density in ultrafast laser-matter interactions.
    • This control offers potential for accelerated and precise surface structure processing.
    • The study highlights a novel approach to enhance laser-induced material modification.
