The contact spacer is the core component of flexible tactile sensors, and the performance of this sensor can be adjusted by adjusting contact spacer micro-hole size. At present, the contact spacer was mainly prepared by non-quantifiable processing technology (electrospinning, etc.), which directly leads to unstable performance of tactile sensors. In this paper, ultrathin polyimide (PI) contact spacer was fabricated using nanosecond ultraviolet (UV) laser.

In this paper, a feasibility study of manufacturing anti-bacteria surface on stainless steel 7C27Mo2 used for surgical tools by using nanosecond pulse laser is presented. The effect of laser power on the depth of groove was studied through laser cutting experiment. Micro-pillar arrays of different dimensions and spacing were generated by laser cutting. The wetting characteristics of micro-structured surfaces were assessed by using the static contact angle measurement approach. The measurement results show that the original hydrophilic stainless steel surface can be converted into a hydrophobic surface by using laser structuring as the contact angle can be doubled. This research shows that it is feasible to manufacture hydrophobic microstructures with a laser cutting process.

Abstract:
Optical fiber lasers have significantly influenced modern photonics, becoming indispensable tools across various industries and research fields. By exploiting the guiding properties of rare-earth-doped optical fibers, fiber lasers achieve efficient amplification and high beam quality through population inversion stimulated by diode-pumped architectures. Pulsed fiber lasers, in particular, have evolved to offer precise temporal control, high peak powers, and ultrashort pulse durations ranging from nanoseconds to femtoseconds. Various pulse generation mechanisms, including gain-switching, active and passive Q-switching, and mode-locking, are discussed, highlighting their respective operating principles, pulse characteristics, and application scenarios. Critical system components—such as pump sources (typically diode lasers), fiber resonators utilizing Bragg gratings or ring resonators, modulators, saturable absorbers, and effective dispersion management—are examined in detail, emphasizing their roles in enhancing performance, reliability, and efficiency. Nonlinear optical phenomena inherent to fiber lasers, including self-phase modulation, stimulated Raman scattering, and four-wave mixing, significantly influence pulse formation and stability, necessitating careful dispersion and nonlinear management strategies. Advanced methods such as chirped pulse amplification (CPA) have facilitated the generation of high-energy femtosecond pulses crucial for demanding scientific and industrial applications. Pulsed fiber lasers have rapidly penetrated diverse sectors including precision materials processing, biomedical surgery and imaging, high-capacity optical communications, LiDAR-based remote sensing, and fundamental scientific research. The chapter concludes with a forward-looking perspective, emphasizing the ongoing challenges and anticipated technological innovations that will continue driving fiber laser development and expanding their capabilities and application domains.

The development of diode pumped solid state lasers with high beam quality improves the quality of laser beam removed micro-structures and opens the possibility to use this technology as a new manufacturing method for producing micro-tools. Predestined materials for the 3-dimensional micro-structuring by laser beam removal are hard materials such as ceramics and hard metals, which can be processed only by time and cost expensive technologies. These tools can be used for forming processes of metal parts, like stamping, embossing or cutting.
