It's also unsaid that one cannot avoid the fiber laser cutting machine when the topic of discussion is laser cutting machines. So, here we are with yet another article based on fibre laser cutting machines. This is the time to decode everything about fibre laser-cutting machines!
What Is Meant By Fiber Laser Cutting?
When it comes to fiber laser cutting, it utilises a type of solid-state laser in order to melt or pierce various substances and achieve an accurate cut. The laser medium for this specific technology is optical fibre, as opposed to crystal or gas. By understanding that a laser is a concentrated light, it is obvious that optical fibre can intensify the beam; hence, this is why fibre is known to be the active gain medium which is utilised to increase the laser to a higher power level.
Fibre laser cutting machines can cut a wide range of materials and varied thicknesses depending on the machine's capacity. Today, most fibre laser cutting machines can cut stainless steel that goes up to 10mm thick. Also, a fibre laser cutting machine is helpful in cutting sheet metals, encompassing copper, brass, carbon steel, titanium, and aluminium.
Fibre laser cutting machines excel in cutting reflective substances, which CO2 lasers toil with. This type of laser cutter is generally utilised in manufacturing and infrastructure industries because fibre laser cutting machines are subsequently more pricey when compared to CO2 laser cutters.
Working Principle Of Fiber Laser Cutting Machine
Let's move forward and know how fibre laser cutting machines function. There are a lot of things that many purchasers are not aware of, and one of them is how this machine actually operates. It is always better to gain extra knowledge about something in which you will invest your time, money, and effort.
So, this specific laser machine functions on a laser that is emitted through a fibre laser generator. This laser is produced through an optical path that concentrates the fiber laser beam in the material utilised with an extremely high-power density. Then the laser beam is illuminated the surface of the substance in order to bring the substance to its boiling or melting point.
At this point in time, the high-pressure gas associates with the fiber laser beam and blows out the vaporised or molten material. While all this is done, the laser beam moves in accordance with the substance, breaking down the substance and accomplishing the main objective of cutting.
What Is The History Of Fiber Lasers?
Here is a quick overview of the history of fibre lasers:
- The 1960s - Inception of Lasers
The concept of lasers was first brought in the 1960s, with the first working laser illustrated by Theodore Maiman. A solid crystal was used as a gain medium by this laser.
- The 1970s - Introduction of Optical Fibers
The evolution of optical fibres achieved momentum in the 1970s. Optical fibres are defined as thin strands of glass or plastic that have the ability to transmit light signals over long distances with minimal failure. This laid the foundation for the future expansion of fibre lasers.
- 1980s - Emergence of Fiber Lasers
In the 1980s, initial research and developments were made about fibre lasers and researchers started to explore the possibility of utilising optical fibres as the gain medium. In 1987, Elias Snitzer brought up the concept of a "fibre laser amplifier," which further laid the foundation for the development of fibre lasers.
- The 1990s - Progress and Commercialization
Throughout the 1990s, significant progress was made in fibre laser technology. Researchers improved the efficiency and power output of fibre lasers, making them more practical for various applications. Commercialization efforts also began, and companies started producing fibre laser systems for industrial applications like marking and material processing.
- The Early 2000s - Power Scaling and Wavelength Diversity
The early 2000s is considered a period of immediate advancement in fibre laser technology. Researchers formulated methods for power scaling, authorising fibre lasers to produce higher output powers. Besides, improvements in rare-earth-doped fibres encouraged fibre lasers to be utilised at varied wavelengths, extending their versatility and application bandwidth.
In the past few years, research has been solely focused on pushing the limits of fibre laser enactment, comprising wavelength agility, power scaling, and beam quality improvement. In addition, progress in nonlinear optics has facilitated the generation of new wavelengths through methods such as supercontinuum generation.
What Are The Materials That A Fibre Laser Machine Can Cut?
A fiber laser cutting machine is known as a versatile and powerful tool that has acquired good popularity for its capability to cut through a wide range of substances with efficiency and precision. One of its primary resilience lies in its capability to cut through various metals, such as stainless steel, steel, copper, brass, aluminium, and even more specialised alloys like tool steels or nickel alloys. The focused energy of the fibre laser beam enables quick melting and evaporation of metal surfaces, which results in clean and precise cuts.
Beyond metals, fibre lasers are well-suited for working with other materials like plastics which include acrylic, polycarbonate, ABS, and PETG, these substances can be effectively cut with fibre lasers, however, optimal cutting parameters might vary on the basis of the type of plastic. This ability extends to textiles and fabrics, where fibre laser cutting machines can develop intricate patterns and designs in materials ranging from delicate fabrics to powerful leather.
Fiber lasers are also being used in cutting ceramics, although the brittle nature of ceramics needs extraordinary attention to accomplish desired outcomes. In industries like automotive and aerospace, fibre lasers are utilised to cut through fibre-reinforced composites, which merge layers of different elements like carbon fibre and epoxy resin. For electronics and microfabrication, fibre lasers excel in cutting thin films with utmost precision, contributing to the production of intricate electronic elements.
Types Of Fiber Laser Cutting Machines?
Here are the three types of fiber laser cutting machines:
Low-Power Fibre Lasers:

Medium Power Fiber Lasers:
These fiber laser machines are eligible for operating on a wider range of materials and thicknesses, comprising metals and alloys of medium thickness. They find applications in industries like aerospace, automotive, and machinery manufacturing.
High-Power Fiber Lasers:
The high-powered machines are specifically designed for heavy-duty cutting of thick metals and are generally utilized in industries needing high throughputs, such as construction, shipbuilding, and heavy machinery.
Difference Between Fibre Laser Cutting Machine And CO2 Laser Cutting Machine?
Fiber laser cutters and CO2 laser cutters differ from each other as they are both utilized for different purposes. We have mentioned some of the common differences below, check it out:
Fibre laser produces a shorter wavelength when compared to CO2 laser cutting machines. That is why fiber lasers have great absorption power which helps in enhancing the cutting quality and speed.
- Different Mechanisms Used
Fibre laser cutting machines utilize components such as neodymium, erbium, dysprosium, and yttrium. Combining these elements produces a crystalline solid as a fiber, and then this is directed into the cutting head of the machine via a transport fiber. On the other hand, CO2 lasers utilize carbon dioxide, helium, nitrogen, and various other gases. All these gasses are mixed together to generate a focused laser beam.
As the fiber laser cutting machine is able to quickly process the operation with enough proficiency, it gives out financial advantages when it comes to high-volume manufacturing. Moreover, CO2 laser cutting machines require a warm-up time before starting with the process, which helps in reducing efficiency as well as output.
