摘要： A large-mode-area (LMA) optical fiber (10) that operates as a single-mode optical fiber. The optical fiber includes a core region (20) surrounded by an inner cladding (32), which in turn is surrounded by an outer cladding (40). The inner cladding includes at least one up-doped ring region (32R1). The ring region is configured to form a large attenuation differential between the higher-order modes and the fundamental mode so only that the fundamental mode remains traveling in the optical fiber. If necessary, the optical fiber can include a bend (10B) having a select “resonant” bend diameter (DB) that increases the relative attenuation of the fundamental and higher-order modes. The optical fiber supports an effective mode field diameter (MFD) of up to 40 μm to 50 μm. As a result, detrimental non-linear effects are suppressed, which allows the optical fiber to carry substantially more optical power than conventional LMA optical fibers. The LMA optical fiber is thus eminently suited for a number of optical-fiber-based applications calling for high optical power, such as fiber lasers and pump sources for wavelength conversion.
摘要翻译：作为单模光纤工作的大模（LMA）光纤（10）。光纤包括由内包层（32）包围的芯区域（20），该内部区域又由外包层（40）围绕。内包层包括至少一个上掺杂环区（32R1）。环形区域被配置为在高阶模式和基模之间形成大的衰减差分，从而仅使基本模式保持在光纤中行进。如果需要，光纤可以包括具有选择的“共振”弯曲直径（DB）的弯曲（10B），该弯曲直径（DB）增加了基极和高阶模的相对衰减。光纤支持高达40μm至50μm的有效模场直径（MFD）。结果，抑制了有害的非线性效应，这使得光纤比传统的LMA光纤承载更多的光功率。因此，LMA光纤非常适合于需要高光功率的多个基于光纤的应用，例如用于波长转换的光纤激光器和泵浦光源。
