Precision in Every Pulse: The Power of UV Laser Marking with 355nm Laser Technology

In the world of micro-marking and fine detail processing, UV laser technology has carved out a unique space—especially when paired with the high-performance 355nm laser. As industries demand higher precision and lower thermal impact, UV laser marking is becoming a standard for manufacturers of electronic components, glassware, medical devices, and more.

What is a UV Laser?

A UV laser is a type of solid-state laser that emits ultraviolet light, typically in the 355nm wavelength range. This shorter wavelength allows for cold processing, meaning minimal heat is transferred to the material, which reduces deformation and improves precision.

This makes UV lasers ideal for:

• Plastic marking without burning or discoloration

• Glass engraving with no cracking

• PCB circuit marking

• Ceramic and crystal marking

Why 355nm Laser is the Industry Choice

The 355nm laser, also known as a third-harmonic generation (THG) laser, is the most common UV laser used in industrial applications. It delivers:

• Extremely fine focus spot

• Minimal thermal impact

• High absorption on sensitive materials

• Exceptional precision for microtext, barcodes, and 2D codes

Thanks to its capabilities, 355nm laser systems are widely adopted in semiconductor, electronics, medical, and consumer product industries.

UV Laser Marking: Where Precision Meets Performance

UV laser marking offers unbeatable accuracy, especially where traditional lasers like CO₂ or fiber lasers fall short. It excels in marking:

• Transparent and reflective materials

• Heat-sensitive components

• Complex geometries with tiny features

The result? Permanent, high-contrast, and non-damaging marks that pass stringent quality standards.

Applications of UV Laser Marking

From delicate electronics to high-value branding elements, UV laser marking is used in:

• QR code and serial number engraving

• Logo and branding marks

• Traceability solutions in pharmaceuticals

• Safety-critical component ID in aerospace and automotive

The precise, no-contact, and clean marking process ensures long-term durability and readability.

Conclusion

For businesses looking to upgrade their marking capabilities, a UV laser—particularly with a 355nm laser—offers a perfect combination of accuracy, speed, and material compatibility. Whether you're engraving plastics, ceramics, or glass, UV laser marking technology delivers exceptional results without damaging your products.
