在本文中，我们提出了一个高功率光子晶体光纤激光器的结果，其中众所周知的双包层和大模面积的设计概念转移到一个有源掺杂的微结构光纤。双包层设计是通过用硅桥网（薄至390 nm，长约50 μ/m）包围内包层（泵浦芯）来实现的，硅桥网基本上窄于引导辐射的波长。得出结论，空气包层微结构掺镱大模场面积光纤应可扩展到千瓦级的输出功率，其中非线性将限制性能。
In this paper, we present the results of a high power photonic crystal fiber laser, where the well-known concepts of double-clad and large-mode-area design are transfered to an actively doped microstructured fiber. The double-clad design is achieved by surrounding the inner cladding (pump core) with a web of silica bridges (as thin as 390 nm and approximately 50 /spl mu/m long) which are substantially narrower than the wavelength of the guided radiation. It is concluded that air-clad microstructure ytterbium-doped large-mode-area fibers should be scalable to kW-level output powers, where nonlinearity will limit the performance.
