Fiber Laser Cutters Available from SPI Lasers

Laser cutting is just one of many different processes that our high-quality fiber lasers are capable of. While one of our machines is capable of performing multiple processes for varying applications and materials, in this article we explore the laser cutting functionalities of our machines in greater detail.

What is laser cutting?

Laser cutting is the process of cutting a material down using a laser, which differs from more conventional methods that traditionally use a blade. While bladed cutting is still an approach that is used, laser cutting allows for much more precise and clean cuts, reducing material wastage and allowing components and products to be even smaller.

What are the different types of laser cutting?

There are three main types and techniques of laser cutting and laser cutting machines:

Gas laser cutting

Gas laser cutting machines, using C02 gas, is a commonly used form of laser cutting, but with a wavelength of 10.6 micrometres, it is only useful for non-metals.

Crystal laser cutting

Crystal laser cutting, is conducted using nd:YAG (neodymium-doped yttrium aluminium garnet) or nd:YVO (neodymium-doped yttrium ortho-vanadate) laser cutting machines. This process is similar to the fiber laser cutting process, and with a wavelength of 1.064 micrometres, can be used on both metals and non-metals.

Fiber laser cutting

Fiber laser cutting is a process where the core component used is an optical fiber, typically doped with rare elements such as erbium, thulium and dysprosium. A fiber laser cutting machine has the same wavelength of that as a crystal laser cutting machine, 1.064 micrometres, and so can work with both metals and non-metals.

Fiber lasers from SPI Lasers

Here at SPI Lasers, we have opted for the third laser cutting process; fiber laser cutting. While it may not be the most common of the laser processes, we believe that it is by far the most versatile and beneficial.

We immediately ruled out gas laser cutting due to its inability to work with metals, as this limits its usage in a huge majority of the world’s industries. And while crystal laser cutting and fiber laser cutting bear striking similarities, fiber laser cutting proves to be the more useful and long-lasting process.

This is because a crystal laser cutting machine typically has a service life of between 8,000 and 15,000 hours of use, while a fiber laser cutting machine can last for around 25,000 hours. Alongside this, the replacement parts for a fiber laser cutting machine are much cheaper than the expensive parts for the crystal laser cutting machine.

We have two types of fiber laser machine on offer at SPI Lasers:

Continuous Wave Fiber Laser

A continuous wave fiber laser is a laser that delivers a constant flow of laser energy over the material that you are cutting. We have a range of continuous wave lasers, with capabilities ranging from 100W to 6kW.

The continuous wave fiber lasers that we stock at SPI Lasers are:

Depending on your requirements, different lasers will be more suitable. Please speak to one of our team of experts to find out the best avenue for you.

Pulsed Fiber Laser

Our redENERGY G4 Pulsed Fiber Laser emits a pulsed beam, great for delivering highly precise markings or engravings. You can find out more on our pulsed fiber lasers from our product data sheet here.

You can also see our pulsed fiber lasers in action here: redENERGY G4 Pulsed Fiber Laser Cutting & Marking 0.3mm & 0.9mm Copper.

We have a number of fiber lasers capable of laser cutting on offer at SPI Lasers, such as these pulsed fiber laser above

Which is the right cutting laser for your application?

Whether it is a pulsed fiber laser machine or a continuous wave fiber laser machine, we have built them to be long-lasting and with low maintenance costs. While we have different lasers to suit different capabilities, whatever the process is that you need to complete, we can help.

Thanks to the efficiency, quality and reliability that our lasers offer, they are used in many industries around the globe. This includes in the aerospace, automotive, electronics, semiconductor and medical sectors.
