CW Lasers FAQs

We’re regularly asked various questions on CW lasers by our clients and customers. Whether you’re new to the industry or you’ve been using fiber lasers for years, you’ll agree that CW lasers are a complex topic involving plenty of information!

We’ve laid out some of the most frequently asked questions regarding CW lasers below, you may also want to read our CW glossary of terms page.

What are CW lasers?

While we’ve covered this a little more extensively in the section titled ‘What is a Continuous Wave (CW) Laser’, this is a common question that we get and we expect customers to come here looking for a quick answer!

In short, the clue is in the name when it comes to a CW laser. A CW laser is a laser that provides a continuous wave of energy, as opposed to a pulsed laser, which delivers similar results but in pulses.

What is the benefit of using a CW laser over a pulsed laser?

Pulsed fiber lasers are useful if you are looking for total control over your beam, and are perhaps working within very tight margins. Continuous wave fiber lasers, on the other hand, deliver a quicker, more powerful wave of energy to result in a clean cut or weld.

You’ll more often see this type of laser being used in industrial settings, where efficiency and effectiveness are the top priorities, as well as stability.

What processes can be completed using CW lasers?

The main processes that are completed using CW lasers are laser welding, laser drilling and laser cutting. While laser cutting and laser drilling are very similar, they are two separate processes in their own right.

What materials can CW lasers work with?

Our fiber CW lasers are the tool of choice for many industries looking to quickly process applications involving metals and reflective metals; they are also increasingly being utilised in the developing additive manufacturing industry.

What industries are CW lasers used in?

CW lasers are used in a wide variety of industries, with the most common being the aerospace, automotive, electronics, semi-conductor and medical industries. For more information on the specific industries that we operate within, and how CW lasers help, please refer to the sections at the bottom of this page.

What beams do CW lasers use?

CW lasers use three main types of gain medium; gas, crystal or fiber. Here at SPI Lasers we only stock fiber CW lasers, the newest of the three types of lasers. While they all have their own advantages, fiber lasers offer the most to consumers in terms of power and cost reductions.

The three different types of laser beam all operate along different wavelengths, with gas lasers being the most common type on the market.

What does OEM mean?

Many of you will already be familiar with this type, but for those that aren’t OEM stands for ‘original equipment manufacturer’. This means that we produce CW lasers as our own, but often these are incorporated into other machines or setups that won’t be sold under the SPI Lasers name.

Many of the end products that you use every single day will have been constructed using parts from various OEMs.

What’s special about your redPOWER CW Lasers?

We’ve built our range of CW lasers to last, and they feature some of the most modern and up-to-date innovations available. This includes our “Fit & Forget Technology”, which has become a favourite among our clients.

Our CW lasers have extremely low maintenance costs and times, and our Fit & Forget Technology means you rarely ever have to worry about servicing!

While we appreciate that our lasers are most often used in heavy industrial settings, we do place a special focus on the environment too. With this in mind, all of our CW lasers have a low carbon footprint, by using fewer chemicals and less energy.

How powerful are your CW lasers?

Currently, our CW lasers operate in the range of 300W to 6kW. The power output that you need is heavily dependent on the industry that you operate in or the material that you plan to be working with.

If you’re unsure which is the best laser for you, please contact us using the details listed below and we will be happy to answer any questions you may have.

Are your CW lasers covered by warranty?

Yes – any CW laser that you purchase from SPI Lasers will be covered by a three-year warranty.
