The invention discloses a method for preparing a continuous gentle micro-nano structure on a titanium substrate from the outside to the inside through femtosecond laser processing and then anodizing. The method comprises the three steps of polishing, femtosecond laser processing and anodizing. The continuous gentle micro-nano structure prepared through the method is good in repeatability, high in stability and controllable in size and has excellent mechanical properties and biological properties. Due to the fact that the continuous gentle micro-nano structure is formed by partially converting an implantation material and no obvious separatrix exists between the structure and the substrate, the combination strength of the structure and the titanium substrate is high; in addition, the continuous gentle concave pit structure is more approximate a natural bone structure, and osteoblast adhesion growing is facilitated.
