What Is a UV Laser?

A UV laser (ultraviolet laser) is a short-wavelength laser that typically operates at 355 nm or lower. Because UV light carries higher photon energy compared to infrared or visible lasers, it enables "cold processing" — material removal without significant heat.

This results in extremely clean edges, minimal thermal impact, and unparalleled precision, making UV lasers ideal for micro-marking, delicate material processing, and applications where traditional lasers may cause damage.

UV Laser Marking: High Precision Without Heat

UV laser marking involves using a focused ultraviolet beam to mark logos, serial numbers, barcodes, and traceability codes on materials without altering their structure or causing burns.

UV laser marking is widely used in:

• Electronic components (ICs, PCBs, chips)

• Medical devices

• Pharmaceuticals (anti-counterfeiting codes on bottles)

• Plastics and polymers

• High-end glass and ceramic products

The advantage of uv laser marking is that it works on materials that are sensitive to heat or prone to deformation, providing sharp, high-contrast marks with minimal surface damage.

UV Laser Engraving: Micron-Level Detail

Unlike marking, UV laser engraving is used to remove material and create deeper structures. It’s perfect for:

• Microfluidic chip engraving

• ID card security features

• QR code engraving on transparent plastics

• Semiconductor scribing

Thanks to the ultra-fine spot size and shallow penetration, uv laser engraving is the go-to choice for applications that require micron-level accuracy with low heat stress.

Deep UV Laser: Going Beyond 355 nm

A deep UV laser refers to lasers with wavelengths even shorter than 355 nm, such as 266 nm or 193 nm. These are used in highly specialized fields like:

• Photolithography for semiconductor wafers

• DNA and cell-level bio-processing

• Nanofabrication of optics and microstructures

• Transparent material micro-drilling

The energy of a deep uv laser is sufficient to break molecular bonds, enabling direct interaction with material surfaces at the atomic level — a capability that few other technologies can match.

High Power UV Laser: Speed Meets Accuracy

For high-speed industrial applications, a high power uv laser provides the energy needed for rapid processing without sacrificing precision.

Key benefits include:

• Higher throughput in production lines

• Capability to process harder materials like glass and sapphire

• Support for multi-layer PCB marking and cutting

• Ideal for inline integration in electronics and solar panel manufacturing

High power uv lasers are now widely adopted in consumer electronics, medical manufacturing, and even aerospace micro-component production.
