Abstract The influence of laser fluences and scanning speeds on the morphologies of laser-induced periodic surface structures(LIPSS) on heated LiNbO3:Fe(1000○C) surfaces was investigated under femtosecond(fs) laser scanning irradiation. Laser fluence of 8.5 kJ/m2 and scanning speed of 1 mm/s were found to be optimum process parameters, and large-area fs-LIPSS on LiNbO3:Fe with an area of 8 mm×8 mm were fabricated with these parameters. The wettability of laser-textured LiNbO3:Fe changed to be hydrophilic, and the absorptance was improved substantially in the spectral range of 400-2000 nm. This technique is efficient, and environmentally friendly, which will attract tremendous interest in nano-photoelectron and nano-mechanics.
