Ultrafast laser marking machines mainly include femtosecond lasers and picosecond lasers. Because of their extremely short pulse width and extremely high peak energy , they can perform ultra-fine processing on the material surface without heat impact . Therefore, it is widely used in high-precision and high-requirement industries , mainly including the following fields:

Semiconductor and electronics industry

Ultrafast lasers can perform fine processing without generating thermal effects, making them particularly suitable for the manufacture of semiconductor wafers, electronic components and display panels.

• Wafer manufacturing and packaging : Fine micro-machining such as dicing, scribing and drilling is performed on wafers.

• PCB and FPC circuit boards : can be used for precision circuit cutting and micro-hole drilling, ensuring high precision without damaging the substrate material.

• OLED and LCD display technology : used for cutting and repairing glass substrates and flexible display materials.

Medical Devices and Biotechnology

Since ultrafast lasers do not produce heat-affected zones, they are suitable for high-precision medical device processing.

• Heart stents, orthopedic implants : ultra-fine engraving and marking of materials such as titanium alloys and stainless steel.

• Biomedical microfluidic chips : fabrication of microfluidic structures for experimental and diagnostic analysis.

• Ophthalmic surgery : Femtosecond lasers have been widely used in corneal surgery, such as LASIK (myopia correction).

Precision machinery and watch industry

Ultrafast laser technology can perform non-destructive processing on high-hardness materials, making it an important technology in the watch and precision machinery industry.

• Watch engraving and decoration : engraving fine patterns on dials, hands and movement parts.

• Micromachining : High-precision cutting and marking on tiny parts, such as aerospace precision parts.

Automobile and aerospace industries

Ultrafast lasers can perform fine processing on high-strength and composite materials, ensuring the strength and accuracy of parts.

• Aircraft engine parts : microstructure processing on titanium alloys and high-temperature alloys.

• Automotive interior and exterior trim : Used for fine marking on automotive glass, instrument panels and buttons.

Jewelry and high-end crafts

• Precious metal engraving : Fine engraving on precious metals such as gold, silver, platinum, etc. will not produce heat-affected zones, ensuring that the material does not deform.

• Diamond and gemstone micro-engraving : tiny patterns or anti-counterfeiting marks can be engraved on the surface of gemstones.

Research and material development

Ultrafast laser technology is widely used in scientific research, especially in the exploration of new materials and microstructure manufacturing, such as nanomaterial processing, optical thin film cutting, and metamaterial manufacturing .

Ultrafast laser marking machines have become an indispensable tool in the field of high-end manufacturing due to their high precision, no heat impact and multi-material adaptability. It is suitable for industries that require extremely high processing accuracy and quality, bringing more sophisticated and reliable marking and processing solutions to modern industry.
