• first time, we demonstrated the fabrication of ladder-like LIPSS over a large area, with controllable periodicities ranging from 250 to 1200 nm by selecting the appropriate femtosecond laser irradiation wavelength. These controlled nanoscale LIPSS can be created over a large surface area, limited only

• . At 355, 532 and 1064 nm, no coloration of the sample was observed. The femtosecond laser irradiation at 800 nm also induced defects, again observed as brown coloration. The absorbance spectra indicated that this coloration was related to the formation of oxygen deficiency defects. After annealing
