Fiber laser

（重定向自Fibre laser）

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, thulium and holmium. 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.

单词	Fibre laser
释义	Fibre laser 原声例句经济学人-科技 In the case of Dr Sweeney's fibre laser, the beam will have a wavelength of 1.5 microns, making it part of the infra-red spectrum. 以斯威尼(Sweeney)博士研发的光纤激光器为例，它产生的激光波束波长为1.5微米，这使其成为红外线光谱的一部分。经济学人-科技 The beam itself will be produced by a device called a fibre laser, this generates the coherent light of a laser beam in the core of a long, thin optical fibre. 激光波束本身将由光纤激光设备产生并在一个细长的光纤核心产生激光束的相干光。英语百科 Fiber laser （重定向自Fibre laser） 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, thulium and holmium.
