1. Wavelength

Most fiber lasers emit light in the 1064 nm range of the near-infrared spectrum. This wavelength is ideal for engraving on metals and certain polymers because of its strong absorption.

Lasers in the ultraviolet range (about 355 nm) operate at shorter wavelengths. In contrast to fiber lasers, this wavelength has a unique set of interactions with various materials.

2. Material Compatibility

This product works great with metals, alloys, plastics, ceramics, complex materials, and polished metals. It is not appropriate for transparent plastics, glass, or organic materials like wood, which do not easily absorb this wavelength.

UV lasers are compatible with more materials than other lasers, including glass, certain polymers, ceramics, semiconductors, and delicate materials.

Materials that do not absorb infrared light may be marked and engraved easily.

3. Precision

Fiber lasers are rapid and precise so they can engrave complex patterns quickly. They can mark metal surfaces with great quality and precision.ComMarker B4 cuts with a precision of 0.01mm.

UV lasers provide pinpoint accuracy and enable the creation of minute features on a wide range of substrates. However, they could have somewhat slower processing rates compared to fiber lasers.

4. Heat Production:

Some materials may be damaged by the heat generated by fiber lasers during the engraving process. However, their influence is often smaller compared to other kinds of lasers.

The engraving process with a UV laser produces less heat than with other laser types, which is beneficial for engraving heat-sensitive materials.

5. Expense and Upkeep:

Although fiber lasers may be more costly initially, their reduced maintenance costs and greater efficiency make them a better investment in the long term.

Due to the complexities of dealing with shorter wavelengths and the requirement for more sensitive optics and components, UV lasers may have greater maintenance expenses. They may have a higher entry price than fiber lasers.

Working Principle

A laser is used in laser engraving equipment to evaporate or melt a substance that is being engraved. The finished product is a permanent engraving that can never be removed.

Laser Beam Generation

Generating a laser beam is the first step in the laser engraving process. An invisible 1064nm light beam from the laser source is the most frequent kind of laser used for engraving. 

Focusing the Beam

After the laser beam is focussed by a set of lenses and mirrors, it is applied to the surface of the material being engraved. The energy of the beam is focused onto a pinpoint area, increasing the temperature at that location dramatically.

Material Interaction

The extreme heat from the laser beam causes the substance to evaporate on contact for those having a low melting point. A tiny crater is left behind as a lasting reminder of this vaporization process.

Finishing the Engraving

Once the laser beam has scanned the whole surface of the material, the engraving process is complete. The engraved text or image cannot be removed from the substrate in any way.
