摘要	Manipulation of material properties via femtosecond laser-induced periodic surface structures is of significant importance for many practical applications in optics, tribology and wettability, but it is still a substantial challenge for single-beam femtosecond laser irradiation. We here report a strategy to uniformly generate large-area periodic nanostructures on molybdenum surface by utilizing cylindrical focusing of double time-delayed femtosecond blue lasers with orthogonal linear polarizations. It is found that three different types of periodic surface structures can be controlled and actively transformed through properly adjusting the energy fluence ratios between double laser pulses. The remarkable long-range uniform property is clearly identified by both the microscopic observation and Fourier frequency analysis. The obtained minimum structural size and period approximate 140 nm and 260 nm, respectively. The underlying mechanisms are attributed to the complex surface plasmon excitation during the temporally correlated dynamic process of dual laser-material interactions. These investigations help to facilitate femtosecond laser nanostructuring into a robust and versatile way. © 2023 Elsevier Ltd
