Fiber lasers are relevant in amplifying light. They work on the principle of using optical fibers that are added to other materials most especially rare-earth halides. The latter is used as the lasing medium in the process. The concepts behind these types of lasers are somewhat the same as those of laser diodes and gas lasers.
With the aid of fiber optics, laser beams are delivered. This deviates from traditional systems like those that rely upon optic resonators and the so-called beam delivery method. With the use of the more modern technologies in fiber optics, fiber lasers avoid controversies on contamination, alignment and maintenance. The different applications for the product include material processing, medicine, spectroscopy and telecommunications. There are a lot of advantages of using these lasers when compared to other types. The designs of these industrial products are varied as well. Learn more about these facts.
Five main advantages
There are five main advantages of using fiber lasers over other media. First is the fact that the light is joined to a very flexible fiber. This allows the fiber to freely move in laser cutting, folding and welding of several metals and polymers.
The next advantage is its capacity to provide extensive power output that can extend for several miles long thus resulting in higher optical gains too. The third benefit can be seen in its optical quality as it prevents or eliminate problems on the optical path’s thermal distortion. This, in turn, produces an optical beam that is of very high quality. The fourth advantage its compactness when compared to either gas or rod lasers. This makes it able to save space too. Lastly, they are reliable because they are stable even when there is vibration. Furthermore, there is no need to make a lot of turnkey operations.
There are two laser designs for fiber lasers. The first one makes use of double-clad fibers that are highly favoured in the fiber laser industry. Such manufacturing design is termed as such because the fiber core is surrounded by two cladding layers. The core is where the lasing mode propagates while the inner layer of the clad is where the beam of light pumps and spreads. It is in the outer cladding where the pumped light is confined.
The second design is known as power scaling. This manufacturing technique is termed as such because it construes with the recent developments introduced in the world of fiber laser technology. These are available commercially together with the market of fibers and the different components in the process.
Most laser marking techniques involve either engraving the mark into metal or plastic components or ablating a surface layer to reveal a contrasting material underneath. Both processes usually require high energy pulsed laser systems and of course involve process debris. Fiber lasers are now a robust industrial tool with a unique series of capabilities that enable a wide range of precision materials processing manufacturing methods.
