Why does all of this make a fiber laser so useful? —Lisa from Ruijie fiber laser cutting machine
One of the biggest benefits that a fiber laser offers to its users is that it is extremely stable.
Other normal lasers are very sensitive to movement, and should they get knocked or banged, the whole laser alignment will be thrown off. If the optics themselves get misaligned, then it can require a specialist to get it working again. A fiber laser, on the other hand, generates its laser beam on the inside of the fiber, meaning that sensitive optics aren’t required to have it working properly.
Another huge benefit in the way that a fiber laser works is that the beam quality that is delivered is extremely high. Because the beam, as we’ve explained, remains contained within the core of the fiber, it keeps a straight beam that can be ultra-focused. The dot of the fiber laser beam can be made incredibly small, perfect for applications such as laser cutting.
While the quality remains high, so too does the level of power that the fiber laser beam delivers. The power of a fiber laser is constantly being improved and developed, and we now stock fiber lasers that have a power output over 6kW (#15). This is an incredibly high level of power output, especially when it is super focused, meaning it can easily cut through metals of all kinds of thicknesses.
Another useful aspect in the way in which fiber lasers work is that despite their high intensity and high power output, they are extremely easy to cool while remaining highly efficient at the same time.
Many other lasers will typically only convert a small amount of the power that it receives into a laser. A fiber laser, on the other hand, converts somewhere between 70%-80% of the power, which has two benefits.
The fiber laser will remain efficient by using near-to 100% the input that it receives, but it also means that less of this power is being converted into heat energy. Any heat energy that is present is evenly distributed along the length of the fiber, which is usually quite long. By having this even distribution, no part of the fiber gets too hot to the point where it causes damage or breaks.
Finally, you’ll also find that a fiber laser works with low amplitude noise, is also extremely resistant to heavy environments, and has low maintenance costs.
