摘要： A method for determining a position of a selected area of a sheet of material relative to a reference plane includes launching a first incident light beam at the selected area of the sheet of material such that the first incident light beam strikes the selected area at a first position and a first angle, thereby producing a first reflected light beam. A second incident light beam is launched at the selected area of the sheet of material such that the second incident light beam strikes the selected area at a second position and a second angle, thereby producing a second reflected light beam. The second position and second angle are different from the first position and first angle, respectively. The first reflected light beam and the second reflected light beam are intercepted at the reference plane. Information related to positions at which the reflected light beams were intercepted and angles at which the incident light beams were launched were received and correlated to the position of the selected area relative to the reference plane.

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。
