Laser Applications For Permanent Marking

About Laser Marking and Engraving 

Laser marking applications involve permanent industrial processes that use a beam of concentrated light to alter the surface of a part. The term "laser marking" actually represents several types of laser applications, including laser engraving. 

Laser marking and engraving applications vary widely and are used across a variety of industries and materials. Laser applications like marking, etching, engraving, and carbon migration allow manufacturers to create important identifying marks on their products, including barcodes, QR codes, serial numbers, date codes, and more. Laser technology can also be used for a wide range of processes, such as bonding, welding, and cutting. These automated marking technologies saves time, reduces waste, and can enable part traceability -- a critital element of Industry 4.0. 

Types of laser applications include: 

Laser Marking 
Laser Etching and Engraving
Carbon Migration
Laser Annealing
Laser Bonding
Laser Cutting
Laser Discoloration
Laser Welding
Laser Ablation

Benefits of Laser Part Marking

Laser part marking technology is growing in popularity among many manufacturers thanks to its numerous operational advantages.

While there are several different types of laser processes, they share many similar benefits, including:
  • Permanent and readable marks
  • High-speed operations
  • High-contrast marks
  • No contact
  • Minimal consumables
  • Marks metals, plastics, rubber, paper/cardboard

Laser Part Marking and Traceability

Part traceability, the capacity for tracking a component and its relevant history throughout its life cycle, is more important than ever in today’s industrial environment.

The growing complexity of supply chains in addition to the threats of counterfeiting and product recalls have prompted many modern manufacturing operations to implement high-quality permanent laser part marking systems. These systems are able to link unique identifiers – such as 1D linear barcodes or 2D matrix codes – to a computer-enabled database via MECCO’s EtherMark technology or custom graphical user interfaces (GUIs).

The marked codes can provide invaluable track and trace information, such as part number, lot number, and manufacturing date.

Laser Marking and Engraving Various Materials

Laser marking and engraving systems can mark a wide range of both organic and inorganic materials. Based on your specific application and requirements, our experts can help you decide if a fiber laser, VP MOPA laserCO2 laser, green laser, or UV laser marking machine is right for you.


Fiber lasers use an optical fiber doped with rare-earth elements such as ytterbium. They are versatile marking systems that mark the widest variety of metals and plastics, including:

  • Steel and stainless steel
  • Bare and cast aluminum
  • Copper
  • Titanium
  • Plastics


For a lower wattage laser that specializes in brighter, crisper marks on plastics and aluminum, MECCO offers a unique diode-pumped laser with patented diodes pumping YAG Crystal.

This type of laser uses a higher peak power to remove paint, anodization, and oxide 25-50% faster while brightening the base material significantly.


Marking parts composed of organic materials, such as wood, glass, plastic, or rubber? The CO2 laser is a carbon dioxide continuous wave laser that is ideal for marking these types of materials.

Carbon Migration

Carbon Migration 

Commonly used in the medical industry for its ability to make clean, hygienic marks, carbon migration occurs during the heating of metal or metal alloys, causing the metal to chemically bond with traces of carbon molecules at or near the part’s surface, creating a dark – sometimes even black – permanent mark.

Laser Annealing

Laser Annealing

Laser annealing refers to localized heating that changes the color of the material being heated depending on temperature of the heat. Popular for marking metals, annealing leaves smooth, dark, non-oxidizing marks.

Laser Bonding

Laser Bonding

Laser bonding, great for a variety of metals, glass, ceramic, and plastic, is unlike any other type of laser application in that it is an additive process that affixes material to the surface/part that is being marked.

Laser Cutting

Laser Cutting

Laser cutting is fast, precise, and delivers a high-quality finish through a non-contact process at a defined focal length. Cut high-precision patterns out of a variety metals, including steel, titanium, aluminum, and copper as well as some plastics and glass.

Learn More about Laser Cutting

Laser Discoloration

Laser Discoloration

Used in automotive, electronics, and medical industries, laser discoloration on plastic happens when color is changed from the pigments or additives interaction with the laser’s localized heating.

Laser Etching and Engraving

Laser Etching and Laser Engraving

Laser etching and engraving can be done on almost any part, making it a great solution for traceability in a variety of industries. The mark left by laser engravers and laser etching is permanent, weather-resistant, and durable for a variety of applications.

Laser Marking

Laser Marking

Laser marking is a permanent process that leaves a lasting mark on a surface through a variety of methods. This marking can be done with a pulsed or continuous wave laser to add barcodes, unique identification numbers, and other valuable traceability information.

Laser Welding

Laser Welding

Laser welding, most prominent in the automotive industry, utilizes a laser beam as a concentrated heat source to join multiple pieces together. Delivering a focused heat source, laser welding creates a strong seam at a high speed.

Layer Ablation

Layer Ablation

Laser ablation involves removing a layer from the surface of a part. Individual layers can be ablated without damaging the underlying surfaces, making it an ideal solution for a number of industries.
