英文摘要	the origin of high-spatial-frequency laser-induced periodic surface structures (hsfl) driven by incident ultrafast laser fields, with their ability to achieve structure resolutions below lambda/2, is often obscured by the overlap with regular ripples patterns at quasi-wavelength periodicities. we experimentally demonstrate here employing defined surface topographies that these structures are intrinsically related to surface roughness in the nano-scale domain. using zr-based bulk metallic glass (zr-bmg) and its crystalline alloy (zr-ca) counterpart formed by thermal annealing from its glassy precursor, we prepared surfaces showing either smooth appearances on thermoplastic bmg or high-density nano-protuberances from randomly distributed embedded nano-crystallites with average sizes below 200 nm on the recrystallized alloy. upon ultrashort pulse irradiation employing linearly polarized 50 fs, 800 nm laser pulses, the surfaces show a range of nanoscale organized features. the change of topology was then followed under multiple pulse irradiation at fluences around and below the single pulse threshold. while the former material (zr-bmg) shows a specific high quality arrangement of standard ripples around the laser wavelength, the latter (zr-ca) demonstrates strong predisposition to form high spatial frequency rippled structures (hsfl). we discuss electromagnetic scenarios assisting their formation based on near-field interaction between particles and field-enhancement leading to structure linear growth. finite-difference-time-domain simulations outline individual and collective effects of nanoparticles on electromagnetic energy modulation and the feedback processes in the formation of hsfl structures with correlation to regular ripples (lsfl).
