Laser implantation preparation method for multi-dimensional continuous fine structure

Abstract

The invention relates to a laser implantation preparation method for a multi-dimensional continuous fine structure, and belongs to the fields of surface fine structure processing and micro / nano technologies. Through 3D printing type scan feeding of a movable three-dimensional fine platform in combination with repeated irradiation of laser light, a multi-layer fine structure is prepared on a substrate by continuously supplementing a suspension containing fine particles. According to the method, a multi-layer fine structure of the same material and a multi-layer fine structure of different materials can be prepared on the substrate. Through adoption of the method, the bonding strength among layers of an implanted fine structure can be enhanced, and the bonding strength and appearance of the implanted structure can be improved. In the method, laser light does not directly act on a target material, so that melting and vaporization of the target material are avoided, and the repeating accuracy of a scanning track can be ensured.

Problems solved by technology

[0006] The existing technology "laser-induced forward transfer", also known as "laser direct writing manufacturing technology", uses laser light from a laser to excite molten jets and droplet jets on thin film targets such as gold and silver, and shoots to the substrate. It has achieved great success in the preparation of discrete surface microarrays. However, because the target is very thin and consumed at one time, it is generally difficult to use the same target for repeated transfer. The continuous surface microstructure difficult to prepare
