Figure | Laser-induced fabrication of TMDC diffractive elements. Laser-induced conversion of thiosalt precursors into MoS₂ (top). Irradiation of the thiosalt precursor (NH₄)₂MoS₄ with structured light induces thermal dissociation, leading to the formation of amorphous periodic structures in the irradiated regions. These structures can be further “developed,” preserving the imprinted pattern on the substrate surface. Subsequent thermal annealing converts the amorphous material into a polycrystalline phase. Examples of diffractive and focusing elements fabricated using this approach are shown below (bottom).
