Picosecond laser marking machines, with their ultra short pulse width and "cold processing" characteristics, are replacing traditional laser equipment in many industrial and medical beauty fields. Its types are usually classified according to laser type (wavelength), pulse width, and device structure, and different classifications correspond to completely different application scenarios.
Infrared picosecond: with a wavelength of 1064nm, it has high absorption rate for metals, strong marking, and minimal thermal impact. It is suitable for metal processing, medical devices, such as UDI permanent marking technology for stainless steel surgical instruments.
UV picosecond: wavelength 355nm, high photon energy, significant cold processing characteristics, minimal thermal impact. Suitable for heat sensitive materials such as electronic components (chips, flexible circuit board markings).
Deep analysis of core application scenarios
Medical device industry: meeting strict regulations
In the European and American markets, the Unique Device Identifier (UDI) of medical devices is required to be directly marked on the device body and must withstand repeated high-pressure sterilization without fading or rusting. Traditional laser marking can produce an oxide layer on the surface of stainless steel, which not only affects corrosion resistance but may also fade during passivation treatment. And picosecond laser captures light by forming nanoscale microstructures on the surface of materials, producing high contrast black marks, perfectly solving this problem.
Automotive industry: achieving functional microfabrication
With the implementation of emission standards in the European market, car manufacturers need to integrate wear indicators (EasyCheck) on brake discs. Picosecond laser can precisely control the engraving depth (such as 90 µ m) with micrometer level accuracy (± 5 µ m), without damaging the substrate or burrs on the edges, meeting the stringent requirements of functional components. Currently, this technology is regarded as the industry benchmark.
Picosecond lasers can also be applied in semiconductor brittle material processing, medical beauty industry, and other fields.
