Transparent medium assisted ultrafast laser surface micro-nano structure preparation method and transfer printing method

The invention discloses a preparation method and a transfer printing method of a transparent medium-assisted ultrafast laser surface micro-nano structure. The preparation method comprises the following steps: covering a target material with a transparent medium; laser penetrates through the transparent medium to act on the surface of the solid target material, and the surface of the target material is machined; and after processing is completed, separating the transparent medium from the target material to obtain the micro-nano structure on the surface of the solid target material. And the in-situ deposition rate of the nanometer material on the surface of the target material is increased by utilizing the mechanical barrier effect of the transparent medium, so that the efficient preparation of the multi-stage micro-nano structure covered by the nanometer material on the surface of the target material is realized. Through the implementation of the method, the in-situ deposition efficiency of the nano material
