The industry of fiber lasers has seen exponential growth in recent years due to being high in demand. From customizing products to carving, industry-level objects, these lasers have found their usage everywhere. From creating unique promotional material, and jewelry to preparing surgical items, fiber lasers are seen as an efficient multipurpose tool.  

Fiber laser engraving is considered of utmost importance, as it is a versatile marking process. It uses a highly focused laser beam to remove material permanently from the desired object’s surface. This process confines itself to a non-contact approach seen as a time-efficient option. Since this technology’s emergence in the 1990s, it has seen significant improvements.

From modern control systems, and high precision to detailing such as maintaining minimum edge roughness, it has shown growth in the metal processing sector. It’s also dependent on opting for high-quality fiber laser engraver to avail of all these benefits. ComMarker excels in this regard, as they provide the B4 fiber laser engraver that provides optimum usability and high-speed production.

It can cut to varying depths and wattage, making it suitable for a broad variety of materials. To understand the prime reasons of fiber laser engraver being the ideal choice for metal processing, we have created a comprehensive article below.

Fundamental Principles of Fiber Laser Technology

Before getting into the depth of fiber laser engraver, it’s important to look into its working and related aspects, as elaborated below.

Fiber Laser Mechanics

With a gain medium as doped silica fiber, this is a solid-state laser. It also contains rare-earth metals containing optical fibers that amplify light. Usually, ytterbium (Yb) or erbium (Er) are used to create the laser beam.

When pump light excites rare-earth ions in the fiber core, the fiber laser activates. Diode lasers produce light at a wavelength that rare-earth ions absorb. Due to the energy transitions of the ions, they release photos. These photos align with the laser’s emission wavelength, producing a concentrated beam of light.

This beam is then focused on a desired metal, and it removes a layer from its surface, making a carving. This can vary in depth according to the setting and speed of the fiber laser engraver. ComMarker B4 works on this principle and works on a wavelength of 1064nm.

Comparison with Other Laser Types

Due to being considered a high-functioning engraver, let’s look at its working as compared to other types of laser engraver.


This type of laser has varying beam quality and slow marking speed, whereas fiber laser beam has low divergence and fast marking speed. Batch production is ideal with fiber lasers, but not as much for CO2 lasers. Fiber lasers also have no maintenance, but CO2 lasers require maintenance, which increases its overall cost.


One of the most popular options, when considered next to fiber lasers, is YAG lasers. In comparison to fiber lasers, these have a high initial cost. Fiber lasers can work with varying depths however YAG lasers, although help in bulk production, can slow down in processing rate when used on thick materials.


This kind of laser is the most affordable among all kinds. They are not as precise as fiber laser engravers. Metals and certain plastics are their limitations regarding materials, however, fiber lasers can engrave on several materials.


The material range of UV lasers is broader than fiber lasers. UV lasers are exceptionally efficient and generate less heat as compared to fiber lasers. Fiber lasers have low maintenance as compared to UV lasers and have a lower cost than these.

Key Components of Fiber Laser Engraver

Laser Source

This generates a high-powered laser beam that performs the markings on the desired surface.

Marking Head

Optical components of the laser are enclosed in this area. A focusing lens, galvo scanner, and beam expander are found within this. Precise positioning of the beam is enabled by this.

Control System

This aligns the interaction between various components of the laser engraver. It receives instructions and generates the appropriate laser to go through previse marking operations.

Workpiece Positioning System

This accurately positions the workpiece according to the marking head. Motorized stages, rotary tables, and positioning systems are a part of this.

Advantages of Fiber Laser Engraving in Metal Processing

Revolutionizing the metal processing industry, fiber laser engravers provide benefits in the following aspects.
