Conceptual model for the principle of composite structuring (IMAGE)
Caption
Ultrafast laser-induced ionized zone can serve as a tunable scatterer to the incident light and lead to the generation of a tunable scattering light field in the focal volume, and this process allows for two parallel material modifications within the extremely compact space of a laser focus and constructing two different yet coupled periodic structures at the same 3D spatial location, namely, single-step composite structuring based on focal volume optical printing.
