Abstract: Abstract In this study, a microsphere-assisted femtosecond (fs) laser temporal shaping fabrication method was proposed. Different from two-dimensional (2D) micro/nanohole pattern, three-dimensional (3D) hexagonal ring-like array can be obtained by microsphere-assisted fs laser double-pulse temporal… read more here.
