Difference between Fiber Laser and CO2 Lasers

The difference falls between the questions of what type of material are you using and how thick is it? The reason for this is because these lasers move at a particular rate, and if your material is too thick, then it won’t work for a particular laser machine. So, you’ll have to choose the right type of laser after you decide on your materials. There are many other factors that make these two lasers different, so we’ll get into it in a second, just keep reading.

The Science

Each laser type has been designed to function at a specific kind of wavelength. The absorption rate is profoundly influenced by the wavelength of the laser, and the angle of incidence. Different lasers have different types of wavelengths like the fiber SSL laser’s wavelength is way smaller at 1 micron than the CO2 lasers wavelength at the 10 microns. So, as you can see, the lasers are going to be good at cutting specific materials, but not all elements. Each has their strengths and weaknesses. You should do your research ahead of time and make sure that the laser you’re choosing to invest in is going to be enough for your personal or corporal projects.

Fiber Laser Cutter

The fiber laser has faster speed than the CO2 laser when it comes to cutting thin materials as the laser can be absorbed quickly and in speed when cutting nitrogen. It cost less than CO2 lasers part for part. It has strict safety precautions because the machine can pass through very narrow openings in the frame of the machine, meaning it can damage the eye’s retina. Lastly, it’s beam guidance is by fiber optics. Therefore, it makes a perfect pick for anyone who knows how to operate protective gear and needs a laser for lighter materials.

CO2 Laser Cutter

The quality is consistent throughout the use of all thicknesses. It’s flexible, high, and suitable for all types of materials. Its CO2 laser tube is better absorbed by the machine frame, which means that there is potentially less risk of damage to the eye and retina. Though, you should still not look directly at the cutting process unless you have the proper protective gear. It’s made from mirror optics, and it can cut with oxygen. Therefore, if you want a safe and effective laser that can cut almost any material out there, then this might be for you. See more.


So how can you tell which laser is better? We’d have to say that both of them are great lasers, but if you’re choosing a safer laser, then the CO2 laser wins. It can cut through almost any material, causes less risk to your eyes, and is built to be durable and reliable for years to come. There are many lasers out on the market, and before you go out and invest in one, you should always do your research. There are many scam lasers, which could end up hurting you and many others around you. So please be careful when you’re purchasing a hobby laser to use.
