Picosecond fiber laser, as a type of short pulse laser, has the characteristic of pulse width at the picosecond level and is widely used in the field of precision machining. Due to its high precision, micrometer level, and even nanometer level processing capabilities, it exhibits unique advantages in material processing, microfabrication, microstructure manufacturing, and other fields. This article will explorePicosecond fiber laserApplication in precision machining.

1、 Precision cutting and punching

In traditional laser cutting, the heat affected area is relatively large, which can easily cause material deformation. Due to its short pulse width and high peak power, it can accurately cut thin films, metals, and high hardness materials, especially suitable for precision cutting with extremely demanding size requirements. It also performs well in drilling, capable of processing micron sized pores, suitable for manufacturing complex microstructures and high-precision micropores.

2、 Micro nano processing

With the development of microelectronics technology, the demand for processing micro nano scale structures is increasing. By using, extremely fine micro nano processing can be achieved without damaging the material. Its excellent focusing performance allows it to etch very small patterns on the surface of materials, which is widely used in integrated circuits, microfluidic chips, MEMS (Micro Electro Mechanical Systems) and other fields.

3、 Manufacturing of metal surface microstructures

Picosecond fiber lasers have high processing accuracy and can be used to manufacture microstructures on metal surfaces, such as micro scale textures, micro grooves, nano scale patterns, etc. These microstructures are widely used in the manufacturing of optical components, sensors, microfluidic systems, lasers, and other precision instruments. The high peak power and high precision of lasers enable them to etch fine structures on the surfaces of different materials such as metals, glass, ceramics, etc., without damaging the overall strength and performance of the materials.

4、 Glass processing

Glass, as a brittle material, is often prone to cracking or fragmentation through traditional processing methods such as mechanical cutting. Due to its short pulse time and low thermal impact, it can accurately cut, drill, and carve on glass surfaces. Especially in the fields of manufacturing optical components, display devices, and microfluidic chips, picosecond lasers can achieve high-precision processing, avoiding the processing defects caused by traditional methods.

The application of picosecond fiber lasers in precision machining has significant advantages. Its high precision, low thermal impact, non-contact processing and other characteristics make it widely used in micro machining, metal cutting, glass processing, microstructure manufacturing and other fields. With the continuous development of technology, its application fields will become more extensive, providing more efficient and accurate solutions for precision machining, and promoting the development of modern manufacturing towards higher precision and intelligence.
