The fiber laser are new technology laser at recent years. The output power of fiber laser can be very high,with good stability.It is a laser in which the active gain medium is an optical fiber. The laser fiber is doped with rare-earth elements. They are related to doped fiber amplifiers, which provide light amplification without lasing. 

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.

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.

The advantages of fiber laser:

Light is already coupled into a flexible fiber.
High output power.
High optical quality
