Abstract

Diffraction-limited 308 W at ∼980 nm from a monolithic ytterbium fiber laser operating at the three-level laser system has been demonstrated, limited only by the available pump power, doubling the previous record and showing significant potential for further power scaling thanks to the availability of high brightness pumps and ytterbium-doped all-solid photonic bandgap fibers optimized for suppressing the four-level system. New record slope efficiencies of 72 % and 81 % for three-level lasers with regard to launched and absorbed pump powers respectively are also set.

衍射限制308 W在~ 980 nm从单片镱光纤激光器

在三能级激光系统中运行的单片镱光纤激光器在约980 nm处产生了衍射受限的308 W，仅受可用泵浦功率的限制，比以前的记录增加了一倍，并且由于高亮度泵浦的可用性和为抑制四能级系统而优化的掺镱全固体光子带隙光纤，显示出进一步功率缩放的巨大潜力。三能级激光器的发射和吸收泵浦功率的斜率效率分别为72%和81%，创下了新的记录。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
