What is a fiber laser?
A fiber laser is a type of laser that uses an optical fiber cable as its gain medium. These lasers fall under the category of solid-state lasers, as they use a solid material as the gain medium, rather than liquid or gas-based lasers like CO2 lasers.
Fiber lasers make use of high-power diode laser sources that convert electrical energy into light (photons). This laser light is then directed through the core of a fiber optic cable, typically made of quartz glass, which contains certain rare-earth elements such as ytterbium or erbium as dopants.
As the light propagates through the fiber cable core, it interacts with a cladding layer made from refractive material. This cladding helps focus the light in a single direction. The light then enters the laser cavity, a small portion of the fiber cable where the laser’s wavelength is determined. The specific wavelength produced depends on the dopant material used within the cavity.
For instance, Gweikecloud often uses ytterbium in its lasers to produce a wavelength of 1064nm. However, fiber lasers can have wavelengths ranging from approximately 780nm to 2200nm.
These wavelengths are considerably lower than those of CO2 lasers, which typically operate at around 10,600nm. The shorter wavelengths of fiber lasers are well-suited for absorption by reflective metal surfaces, whereas CO2 lasers are primarily reflected.
This makes fiber lasers ideal for engraving and cutting metals such as stainless steel, aluminum, brass, copper, gold, and silver.
As the photons enter the laser cavity, they interact with the rare-earth particles, leading to a process called electron excitation. The laser beam is then directed through a focus lens and mirror to generate the final highly concentrated beam.
Why use a fiber laser?
Their main benefit is how well they cut and engrave metals.
Fiber lasers use wavelengths that are absorbed by non-ferrous metals like steel and aluminum, as well as ferrous metals like gold and silver. Diode and CO2 lasers, which have much higher wavelengths, are reflected.
This allows you to make precise engravings directly onto metal surfaces – whereas diodes and CO2 lasers can only engrave coated metals.
Affordable lasers with under 100W power and most commonly used in jewelry engraving and for working on personalized metal products such as flasks, tools, and metal portraits and art.
More powerful industrial fiber lasers, with 100W+ power, are used in industries like aerospace, automotive, electronics, dental and medical, semiconductor, and within the military.
Fiber lasers are most commonly used for engraving metals like steel, brass, silver, and gold, due to their low wavelengths that are absorbed by metal surfaces. This makes them particularly popular for jewelry engraving and metal sheet processing. Industrial fiber lasers are used to make electronics and medical and military instruments, among other applications.
Fiber laser engravers are also extremely precise and fast. For example, high-quality CO2 lasers costing around $5,000 can offer 600mm/s cutting speeds, whereas the ComMarker B4 20W fiber laser costs less than half that, yet can engrave at 15,000mm/s.
Fiber lasers are also more precise than other types of laser. For example, the ComMarker B4 offers an impressive 0.01mm accuracy, while professional models like the 100W JPT provide incredible precision to 0.002mm and even lower.
However, they’re generally more expensive, and have much smaller working areas than diode and CO2 lasers.
Fiber Laser Marking Machine Applications
Fiber laser engravers are incredibly versatile in terms of the materials they can work with. You can use them to engrave a whole range of metals, including steel, stainless steel, silver, copper, brass, aluminum, and alloys.
However, they can also be used with a variety of nonmetal materials, such as:
And plenty more.
The main material they’re not suitable for is wood, for which you’re better of using a CNC router as lasers do not mark wood cleanly.
This versatility makes laser marking machines useful to hobbyists and professionals working across a wide range of different areas and industries. They’re commonly used to mark things like
- Jewelry and ornaments
- Parts (metal and plastic)
- Personalized products
- Home Decor
That being said, not every fiber laser marking machine may suit you. You need to consider the power output, working size, efficiency, and usability factors to ensure you’re choosing the best fiber laser engraver for your needs.
How much does a fiber laser machine cost?
The cheapest fiber laser machines cost under $3,000, although there are only a few to choose from in this price range, such as the ComMarker B4. Industrial fiber lasers can cost tens of thousands of dollars.
Are fiber lasers better than CO2 laser engraving?
FIber lasers are better than CO2 lasers for metal engraving, due to their lower wavelengths being absorbed by metal surfaces, whereas CO2 lasers are reflected. However, CO2 lasers are more suitable for cutting wood and other organic materials. Read our fiber vs CO2 lasers comparison to learn more.
What materials will a fiber laser cut?
Fiber lasers are most commonly used to cut and engrave metals like steel, aluminum, copper, and gold. However, low-power fiber lasers of under 50W can only engrave small depths in a single pass, around 0.3mm, so they’re mostly used for engraving. More powerful 100W lasers can cut some metals up to around 2mm in a single pass.
What can a 50W fiber laser cut?
A 50W fiber laser can cut a variety of metals, but it will likely take multiple passes, as you can expect to cut less than 0.5mm aluminum in a single pass. For this reason, 50W fiber lasers are better suited to engraving, while more powerful machines of 100W and over are better for cutting.
