The nanoscale structure of femtosecond laser-induced modifications known as “nanogratings” has been the subject of speculation and intensive debate throughout the decade since their discovery. The aim of this work is to gain dependable information on the three-dimensional (3D) substructure of nanogratings down to the nanometre scale.
