A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. They are related to doped fiber amplifiers, which provide light amplification without lasing. Fiber nonlinearities, such as stimulated Raman scattering or four-wave mixing can also provide gain and thus serve as gain media for a fiber laser. Fiber lasers are now being used to make high-performance surface-acoustic wave (SAW) devices. These lasers raise throughput and lower cost of ownership in comparison to older solid-state laser technology.

Nd YAG is a crystal that is used as a lasing medium for solid state laser. The dopant, triply ionized neodymium, typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminium garnet (YAG), since the two ions are of similar size.

Nd YAG laser is optically pumped using a flashtube or laser diodes, one of the most common types of laser, and are used for many different applications.

The narrow linewidth fiber laser (narrow linewidth fibre laser) is a fiber laser with narrow laser linewidth.

Laser linewidth is the spectral linewidth of a laser beam. Two of the most distinctive characteristics of laser emission are spatial coherence and spectral coherence. While spatial coherence is related to the beam divergence of the laser, spectral coherence is evaluated by measuring the laser linewidth of the radiation. Although the concept of laser linewidth can have varied theoretical descriptions here this article provides a simple experimental description. One of the first methods used to measure the coherence of a laser was interferometry.

The low noise fiber laser (low noise fibre laser) is a fiber laser with low noise. The low noise fiber laser is effected by the environments, then you will get more accurate results.

You can easily get a high output power such as 100W, 30W , by using fiber coupled lasers. They're used in laser cutting, welding, and folding of metals and polymers.
