An internet search on fiber lasers, or just lasers in general, can turn up dozens of results for you to sift through, and so we wanted to have one handy fiber lasers FAQs section for you here. Whether you’re new to the industry and need some basic knowledge, or you just need a quick question answered, this page is for you!

#1 What is a fiber laser?

In short, a fiber laser is a laser which uses fiber, which has been doped in rare-earth elements, as its medium. This is in contrast to the two main other types of laser on the market; a crystal laser and a gas laser.

#2 Why should I choose a fiber laser?

This is one of the most frequently asked questions that we get here at SPI Lasers, as prospective customers want to know what benefits a fiber laser will offer them over the other types on the market.

A gas laser is the most commonly used laser, but this is because it is the oldest type. A fiber laser, on the other hand, is the newest type of laser to grace the manufacturing world. The reason that we only manufacture and sell fiber lasers at SPI Lasers is because for us there are far more benefits than any other type of laser.

They offer a higher level of efficiency, speed and power, and the maintenance times and costs are dramatically lower than the alternatives. They can also cut reflective materials, often used in many industries, without any damaging back reflections (using our patented back reflection technology). Finally, they offer the user complete control in terms of beam length, duration, intensity and heat output.

#3 Which industries can fiber lasers be used in?

Thanks to the wide ranging benefits that we have listed above, fiber lasers can naturally be used in many industries, due to their ability to work with so many different materials. We’ve covered this in more detail below.

With regards to the industries, the primary industries that we service are:

Fiber lasers are extensively used in the solar industry

Fiber lasers are extensively used in the solar industry

But you’ll also find that fiber lasers can even be used in places such as businesses and schools. You can find out more about the industries that we work in by following the links at the very bottom of the page.

#4 Which materials can fiber lasers be used on?

Fiber lasers are great at working with a huge variety of materials. Below are just some of these many materials:

  • Various metals, including steel, copper, iron, nickel, aluminium, brass and more
  • Silicon Gemstones
  • Plastics
  • Polymers
  • Ceramics
  • Thin films and
  • Brick / concrete

#5 What processes can fiber lasers complete?

There are many fiber processes that fiber lasers can complete, which are:

There is some overlap and similarities between some of the processes, so for more information on each of the processes, please find our links at the bottom of this page.

#6 What applications can fiber lasers do?

If you’ve read the three points above and seen what industries fiber lasers are used within, what materials they can work with, and what processes they can complete, then we’re sure you know they can be used for many different applications! We’ve listed just some of these below:

  • Cutting metals for automobiles, planes, white goods, etc.
  • Printing barcodes
  • Used to assist in artwork
  • Drilling holes to create cooling holes for things such as engines
  • Welding together two similar or dissimilar pieces of metal
  • Helping to clean and smooth out rough edges on diamonds and
  • Cleaning metal surfaces

This barely scratches the surface (much like laser ablation!) of what fiber lasers can achieve so, again, to find out more, please find our contact details at the bottom of the FAQs.

#7 Are there different types of fiber laser?

Yes, there are, and these fall into two broader categories; pulsed fiber lasers and continuous wave (CW) fiber lasers. A pulsed fiber laser is a fiber laser which emits its laser in pulses, useful for when you need to make things such as small cuts and need to take your time with controlled bursts.

A CW fiber laser, on the other hand, emits one long-lasting laser beam, great when you just need to make something like a clean cut quickly and efficiently.

We manufacture both here at SPI Lasers, and you can find out more about pulsed fiber lasers here, and more about CW fiber lasers here.

#8 Fiber or fibre?!

SPI Lasers is an international company that services businesses and industries all over the world, and so we use the American English spelling of fiber laser. However, you may find them also referred to as fibre lasers, taking the UK English version. Don’t get confused, they both do the same thing!
