There are three main categories of fiber lasers: continuous wave (CW) lasers, pulsed fiber lasers, and ultrafast lasers. Continuous wave lasers produce a continuous, uninterrupted beam of light, ideally with a very stable output power. The exact wavelengths or lines at which this occurs is determined by the characteristics of the laser medium. Each laser wavelength is connected with a linewidth, which depends on several factors: the gain bandwidth of the lasing medium and the design of the optical resonator, which may include elements to purposely narrow the linewidth, like filters or etalons.
The fiber laser has many important advantages by itself:
- the output is naturally fiber-delivered, which makes it easy to couple into many laser machine tools and to integrate the easier with robotic delivery systems
- fiber laser high beam quality is suitable to couple it into small fibers, allowing the beam to be focused to small spots in order to obtain the high power densities required for metal welding, cutting, and other industrial processes
- fiber laser architecture lends itself to power scaling
- such fiber lasers have high wall plug efficiency in comparison to CO2 and solid-state lasers, it can also have low maintenance requirements; this lowers the cost of ownership.
Must applications of continuous wave lasers require that the power be as stable as possible over long time periods, as well as over short time durations, depending on the specific applications. To ensure this stability also in the presence of varying environmental situations like temperature, vibrations, and the aging of the laser itself, microprocessor control loops are implemented.
Continuous wave lasers can be useful for a wide range of applications. Such fiber lasers and laser systems based on them are most often and for laser cutting, welding, and drilling tasks, which in itself see uses across dozens of industries. Continuous wave lasers are used in the aerospace and automotive industries to help cut, drill, and well anything from tiny thru-holes that keep engine parts cool, all the way up to cutting huge sheets of metal that form part of the vehicle or aircraft’s final structure. Such fiber lasers are most commonly used for industrial application, the majority of which involve metal in some form, continuous wave lasers find a high prevalence in being used to out, drill, and well metal. In addition to this, this type of the fiber laser is effective in being used upon a wide range of metals, including, but not limited to: steel, brass, nickel, aluminium, tungsten, and suchlike. Moreover, continuous wave lasers are excellent at working with reflective metals too. Such fiber lasers are actively used, additionally, in the medical sector, and it’s not only technologies that these machines are used for, these fiber lasers and laser systems are also used on people too. Powerful continuous wave is being used in trials by oil drilling companies to soften rock to extend the life of drilling heads.
