A fiber laser attempts to seize the ability of fiber optics to be portable and maneuverable and condense that with the electronic power and potential of a highly powerful laser. The gain medium in these instances is very small; the size of the cable, but it can be focused in a multiplicity of ways once the beam leaves the fiber. The different forms of lasers from this method of laser production stem from the rare-earth minerals that are injected into the fiber to enable it to amplify the light that is being emitted. There are some beam-splitting methods that transfer the beam from an active gain to a passive gain medium, instead of simply amplifying the beam as it passes through the fiber.
Since the fiber laser is so moveable, it is considered highly mobile in comparison to some of the other highly calibrated solid-state lasers that are commonly assembled. The power output is quite high because of the small surface area, which means the resultant beam is highly focused and powerful. The optical quality of the beam is strong and well centered because of the multiplicity of elements that are commonly inside the fiber optics of these lasers. Along with the mobility of the laser comes the compact size and composition of the laser along with a reliable laser.
