摘要

在本文中，我们展示了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设计概念被转移到主动掺杂微结构光纤中。双包层设计是通过将内包层(泵芯)包裹在硅桥网(薄至390纳米，长约50 /spl μ m /m)中实现的，该桥网比引导辐射的波长窄得多。结果表明，空气包层微结构掺镱大模面积光纤的输出功率应可扩展到kw级，非线性将限制其性能。

High-power air-clad large-mode-area photonic crystal fiber laser

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.
