Abstract

The invention discloses a surface microstructure-forming system based on coherent laser. The surface microstructure-forming system based on coherent laser comprises a laser generator, a beam-shaping module, a first semireflector and a second total reflector which are sequentially connected along a light path, an electrically controlled movable operating platform is arranged under the first semireflector and the second total reflector, a matrix is placed on the electrically controlled movable operating platform, the first semireflector and the second total reflector are provided with servomotors, and the electrically controlled movable operating platform, the servomotors and the laser generator are connected with a computer. The surface microstructure-forming system based on coherent laser can ensure that melting, convection, vaporization or other physical and chemical processes can take place on the material of the specified part of the surface of the matrix, so that the surface shape of the material can be changed, and thereby a needed periodic surface can be formed; and the technical means disclosed by the invention is simple and feasible, has a positive significance, and is convenient to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of surface engineering and precise manufacturing of functional structures, in particular to a coherent laser-based surface microstructure forming system. Background technique [0002] Periodic microstructured surfaces have various surface functions in different fields. For example, in surface reaction and surface heat transfer applications, the surface condition largely determines the advancement of technology. In terms of biotechnology, the effect of graft integration largely depends on the cycle frequency of the periodic microstructure surface, and the microsurface structure also has a great influence on the behavior of cells. The layered texture can also improve the hydrophobicity of the surface layer, and the addition of microstructured silicon to the photosensor can also improve the spectral sensing range of the photosensor. The specific surface micro-nano structure can also achieve some super properti...
