Two-stage laser-induced synthesis of linear carbon chains

A method is proposed for the synthesis of linear carbon chains under irradiation of colloidal systems consisting of schungite nanoparticles by an ytterbium fibre laser with a pulse duration of 100 ns and an energy up to 1 mJ. Colloidal systems have been previously prepared by laser ablation of a schungite target in distilled water using a Nd³⁺ : YAG laser with a pulse duration of 1 ms and an energy up to 10 J.
