Cicada wing exhibiting a high transparency at wide viewing angles can be bioinspired for the formation of antireflective subwavelength array (ASA), which can effectively enhance surface transmittance of infrared window for infrared detection. Due to extreme fine structure of the ASA and significant limitations of single pulse Gaussian beam manufacturing accuracy, it still a challenge to fabricate ASA with broadband and mechanically-durable properties by femtosecond laser. In this study, a novel temporal-spatial shaping femtosecond laser microma...
