Abstract Inspired by nature, many researchers have noticed that the micro‐ and nano‐structures originated from organism's surfaces which indict unique properties such as superhydrophobicity, drag reduction, structure colour have much use in academic value. However, conventional processing methods for mimicking biomimetic surface need multistep and is time wasted, not environmental friendly and uneconomic. Thanks to the development of ultrafast laser technology, the pulse duration can reach femtosecond scale, which can precisely realize micro‐ and nano‐processing in one‐step. Here, we introduce and demonstrate the principles of some typical properties. The typical structures caused by interaction between laser and material are discussed. Moreover, laser‐processing methods for biomimetic surface are highlighted to achieve specialized performance.
