英文摘要	We report a formation of highly homogenous subwavelength grating structures on the bulk Fe-based metallic glass, using two nondegenerate linear polarization of femtosecond laser pulse sequences at certain temporal delays. In contrast to the previous observations, the well-defined surface structures can take place across the entire laser ablation regions, with the spatial period and the modulation depth of 722 nm and 115 nm, respectively. Through the Fourier transformation analysis, we introduce two parameters to quantitatively evaluate the structure uniformity. The underlying mechanisms are attributed to the surface scattered wave of the second femtosecond laser pulse onto the transient material surface tailored by the first laser pulse. Moreover, different diffusion coefficients of the chemical elements are found responsible for their various removal percentages after laser irradiation.
