The machining of micro/nano periodic surface structures using a femtosecond laser has been an academic frontier and hotspot in recent years. With an ultrahigh laser fluence and an ultrashort pulse duration, femtosecond laser machining shows unique advantages in material processing. It can process almost any material and can greatly improve the processing accuracy with a minimum machining size and heat-affected zone. Meanwhile, it can fabricate a variety of micro/nano periodic surface structures and then change a material’s surface performance dramatically, such as the material’s wetting performance, corrosive properties, friction properties, and optical properties, demonstrating great application potential in defense, medical, high-end manufacturing, and many other fields. In recent years, the research is gradually deepening from the basic theory to optimization design, intelligent control, and application technology. Nowadays, while focusing on metal structure materials, especially on stainless steel, research institutions in the field of micro and nano manufacturing have conducted systematic and in-depth experimental research using different experimental environments and laser-processing parameters. They have prepared various surface structures with different morphologies and periods with sound performance, and are one step closer to many civilian engineering applications. This paper reviews the study of micro/nano periodic surface structures and the performance of stainless steel machined using a femtosecond laser, obtains the general evolution law of surface structure and performance with the femtosecond laser parameters, points out several key technical challenges for future study, and provides a useful reference for the engineering research and application of femtosecond laser micro/nano processing technology.

“…[17,18] An issue with LIPSS is that the structures generated by sequential laser scanning are often misaligned, leading to non-uniformity of LIPSS, which limits their applications that require long-range regulation. [19][20][21][22] Previous studies adopt various methods to enhance long-range SPPs coherence during LIPSS growth process to improve the uniformity. Öktem et al stated that newly generated LIPSS could replicate the characteristics of the existing LIPSS to form uniform nanogratings with regulation from negative local feedback during LIPSS growth process.…”

Laser-induced periodic surface structures (LIPSS) have become an important avenue towards surface nanopatterning and certain device applications due to their subwavelength feature size and versatility with different materials. However, the uncontrollable non-uniformity in achievable nanostructures presents a limit towards its practical application. Here, a robust approach is proposed to obtain controllable nanostructures with long-range order based on a new insight into one of the electromagnetic origins of nonuniformity of LIPSS, namely a half-periodic mismatched optical enhancement (h-MOE) effect. The h-MOE effect originates from the interference enhancement of surface plasmon polaritons (SPPs) located between tips of every two adjacent ripples in laser scanning process. It is found that LIPSS can be self-aligned and highly controllable if the h-MOE effect is elaborately modulated through designed laser scanning strategies especially sequential scanning paths. The new laser nanopatterning approach based on h-MOE demonstrates controllable patterning ability to theoretically infinitely large-area super-straight gratings, orientation-controllable gratings, and half-periodic mismatched nanohole arrays.

“…The study found that the LSFL orientation was not perpendicular to the laser polarization, and the rotation angle increased as the specimen tilted angle increased. In another study, Liu et al [ 15 ] investigated the LIPSS generated by linear polarization (s-polarized and p-polarized) femtosecond laser beam on a tilted SUS 304 surface. The experiments found that LSFL was rotated by the s-polarized beam and was not rotated by the p-polarized beam.…”

“…Hence, the mechanism of rotational LSFL on the tilted specimen by s-polarized laser beam was deduced. However, although [ 14 , 15 ] have published the experimental results for rotational LIPSS on different materials by s-polarized femtosecond laser beam, there is no study to validate whether the LSFL rotates on the tilted surface for more metal materials.…”

Laser-induced periodic surface structures (LIPSS) are used for the precision surface treatment of 3D components. However, with LIPSS, the non-normal incident angle between the irradiated laser beam and the specimen surface occurs. This study investigated LIPSS on four different metals (SUS 304, Ti, Al, and Cu), processed on a tilted surface by an s-polarized femtosecond fiber laser. A rotated low spatial frequency LIPSS (LSFL) was obtained on SUS 304 and Ti materials by the line scanning process. However, LSFL on Cu and Al materials was still perpendicular to the laser polarization. The reason for the rotated and un-rotated LSFL on tilted metal surfaces was presented. The electron-phonon coupling factor and thermal conductivity properties might induce rotational LSFL on tilted SUS 304 and Ti surfaces. When fabricating LSFL on an inclined plane, a calibration model between the LSFL orientation and inclined plane angle must be established. Hence, the laser polarization direction must be controlled to obtain suitable LSFL characteristics on a 3D surface.
