摘要
Both normal and abnormal sub-100-nanometer ripples (wavenumber similar to 10 mu m(-1)) were separately observed on Ti surfaces excited by linearly polarized IR femtosecond laser pulses at lower and higher fluences. Numerical modeling of dispersion curves for surface plasmon-polaritons on the photoexcited Ti surfaces demonstrates its surface plasmon resonance with the peak wavenumber similar to 8 mu m(-1) spectrally tuned by prompt surface optical response, prompt surface charging, and pre-oxidation, with normal/abnormal nano-ripples appearing at its red/blue shoulders, respectively.
