Industrial Lasers

Our redENERGY® and redPOWER® Fiber Laser range comprises fused components, meaning the performance is not dependent on the alignment of rods and mirrors nor can dirt or dust ingress the resonator and deteriorate its properties. For manufacturers using our Lasers, this eliminates the need for time-consuming routine maintenance.

The absence of water-cooled pump chambers negates the risk of leaks that could cause the rods to fail, avoiding service costs. In addition, the use of a doped fiber as the gain medium in Fiber Lasers results in intrinsically stable beam quality, regardless of any heat load, with high brightness and even in fundamental mode, if designed accordingly.

Our Fiber Lasers can be supplied with patented Luminator™ fiber-delivery options, bespoke process tools and scanheads. These ensure safe and reliable 3D manipulation of the Laser beam and positive material processing results.

Our Fiber Laser range includes both rack-mountable and OEM units, offering both air and water cooled options, (mostly) depending on the respective output powers.

How fiber lasers work

There is some brief information listed above on the way in which fiber lasers work, but this is more specifically focused on how our fiber lasers work in particular. Here we wanted to give you a brief overview on how this handy piece of equipment works.

To keep it relatively short, a fiber laser uses an optical fiber as its active medium, which has been doped in rare earth elements, with the most common of these being erbium. These rare earth elements have high energy levels, resulting in a higher power output of the fiber laser.

Unlike other lasers, there is a refractive mirroring system inside the fiber laser core, so all of the activity that is conducted in order to create and emit the laser beam happens from inside the laser. This maximises efficiency in terms of power output. The heat levels of this activity is also evenly spread across the fiber laser, and with an efficient cooling system, the machine will never overheat either.

Finally, it also means that the laser beam that is emitted is able to be controlled to an extremely high degree of accuracy, allowing you to create a laser beam with a pin-point focus, perfect for working with tiny objects and parts. This is beneficial to so many industries, which we will discuss more below.

The advantages and benefits of fiber lasers

Now that you’ve been given a quick science lesson in the way in which a fiber laser actually works, we want to discuss how this translates into benefits and advantages offered.

All our Fiber Lasers benefit from a number of key product qualities that in turn have a direct impact on the performance of our customers products and organisations.

Greater flexibilityGreater flexibility
Our Fiber Laser range offer users greater flexibility based on an extended range of performance features. redPOWER CW HS Laser models benefit from higher modulation rates and closed loop operations, while redENERGY Pulsed EP Series Laser sources offer the greatest range of pulse width variability from 3-500ns with up to 1MHz operation and CW capability.

You’ll also find that flexibility comes in terms of the level of control that you’re offered as a user. The beam duration, length and intensity sits completely in your hands, allowing you to easily switch between several types of laser processes and applications to work with a huge number of materials. This also means that one fiber laser setup is capable of performing a range of different functions.

The benefits of fiber lasers as compared to other laser processes

While we covered the benefits of fiber lasers, and our own fiber lasers in particular, in the section above, you may be asking why you should choose fiber lasers over the other types of lasers on the market.

For a more in-depth review, please read our comparison guide, but we want to highlight the main points here:

  • Fiber lasers have no moving parts, meaning you don’t need to worry about knocking them out of alignment (which means more servicing times and costs)
  • Following from this, fiber lasers have lower maintenance costs and much longer service lives
  • They are much more electrically efficient, delivering a higher power output at a fraction of the electrical cost
  • Pulsed Fiber Lasers are particularly good at working with thin materials, whereas CW Fiber Lasers are great at working with thicker metals
  • They are also the best type of laser on the market at working with reflective metals

Other lasers, with gas lasers being the most common, do have their benefits too, but fiber lasers are the newest type of process on the market, and so have come with the latest developments and innovations. This has all resulted in a high number of advantages.

Fiber laser applications

We covered above the different laser processes that our lasers are capable of performing, so here we want to touch upon some of the applications that these processes can be used for.

Use on reflective metals

This is an important one, as many industries use reflective metals such as aluminium. Our Fiber lasers are brilliant at working with these metals as they have been designed to avoid the reflective nature of the metal damaging the laser.

Scientific research

Fiber lasers have found heavy use in the field of science, both for the creation of tools and equipment, and also for furthering scientific research. Advancements have been made in fields such as spectroscopy, and scientists even predict that fiber lasers will help us build sustainable bases on Mars one day!

Creating electronic devices

Fiber lasers are heavily used in the electronics, batteries and semi-conductor industries, all industries which contribute to the dozens of pieces of electrical equipment that we use every single day. Fiber lasers are great at working with small objects without causing any heat damage to the surrounding area, making them the go-to choice for these industries.

For a much longer list of interesting, useful and sometimes surprising applications, please read more here.

Industries which use fiber lasers

We’ve touched on this briefly above in various places, but here we want to give you a quick overview of the industries which most heavily use fiber lasers:

There are many other industries and places in which you will find fiber lasers being used, but these are the main sectors that we service. The reason that you will find fiber lasers being used in such a wide-ranging number of industries is because of the benefits and advantages that we touched on above.

The fact that the user is able to have total control over beam duration, length and intensity, that one single setup can be used for multiple processes, that so many materials can be worked with and that it’s the most cost-effective laser on the market makes it so attractive.

You can read more on each of the specific industries by following the clickable links at the bottom of this page.

The history of fiber lasers

History fanatic? If you’re interested in lasers and how fiber lasers have started to dominate the market over the last few years, then this section is for you. Fiber lasers have a history dating back to the 1960s, but it’s only been in the last 20 years or so that they’ve really come along in leaps and bounds.

They’ve been developed and improved upon consistently, with the level of power output that they are able to achieve increasing almost year on year. To read more on the history of fiber lasers, please follow this section here.

Fiber lasers in action

We understand that there’s been quite a lot of content on this page! So, to break things up and give you some visual demonstrations, we’ve put together a page with five great YouTube videos that we’ve found that involve fiber lasers.

However, we want to include one on this page too; we couldn’t help including one from our very own YouTube channel! Below you will see our fiber lasers working with reflective metals in order to create a small replica of Tower Bridge, which has come out rather well if we don’t mind saying so!
