Fundamentals of Laser Engraving

One of the most precise and efficient methods of marking materials, laser engraving has become increasingly popular in various industries. This technology uses a high-powered laser to remove the surface material of an object, creating a permanent mark that is highly resistant to wear and tear.

The Laser Engraving Process

When it comes to laser engraving, the process involves focusing a high-powered laser beam onto the surface of the material to be engraved. The intense heat generated by the laser vaporizes or removes the material, leaving a cavity that forms the desired mark. This process is highly precise and can produce intricate designs with exceptional accuracy.

Types of Lasers Used

There are several types of lasers that can be used for engraving, each with its own set of advantages and applications. The most commonly used lasers for engraving are CO2 lasers and fiber lasers.

• CO2 lasers: These are best suited for organic materials such as wood, glass, and plastics. They operate at a wavelength of 10.6 micrometers and are highly efficient for engraving or cutting.
• Fiber lasers: These lasers are ideal for marking metals and hard plastics. They operate at a wavelength of 1.06 micrometers and are known for their high precision and speed.

Perceiving the characteristics of each type of laser will help you determine the best option for your specific engraving needs.
