What is a UV Laser?

A UV laser (ultraviolet laser) is a type of solid-state laser that emits light in the ultraviolet spectrum, typically at wavelengths such as 355 nm. Due to the short wavelength and high photon energy, UV laser systems are capable of extremely fine marking and micro-processing without causing thermal damage to the substrate. This makes UV laser technology ideal for sensitive materials and ultra-precise applications.

The Power of UV Laser Marking

UV laser marking offers exceptional precision and minimal heat-affected zones, making it suitable for industries that demand clean, high-resolution markings. UV laser marking is commonly used on:

  • Plastics and polymers

  • Glass and sapphire

  • Ceramics and silicon wafers

  • Electronic components

  • Medical devices and packaging

Compared to infrared or green lasers, UV laser marking produces superior results on soft or transparent materials.

Deep UV Laser Technology for Micro-Processing

Deep UV laser technology refers to UV lasers with even shorter wavelengths, enabling finer ablation and improved control during microfabrication. The combination of low heat and high precision makes deep UV laser systems indispensable in semiconductor processing, biomedical device manufacturing, and microelectronics.

A deep UV laser minimizes the risk of burning, melting, or discoloring delicate surfaces, offering consistent and permanent marking without post-processing.

Why 355 nm Laser is the Industry Standard

The laser 355 nm (a third harmonic generation of Nd:YAG laser) is widely regarded as the optimal wavelength for UV laser marking. It offers a perfect balance between energy efficiency and marking clarity. A laser 355 nm system can precisely mark plastics without carbonization, and it’s effective for microtext, barcodes, QR codes, and circuit patterns.

Advantages of 355 nm UV Laser:

  • Excellent beam quality and small spot size

  • Ideal for non-metallic and heat-sensitive materials

  • Non-contact, permanent, high-contrast marking

  • Environmentally friendly—no need for inks or solvents
