摘要	In an optical fiber light source a section of multimode fiber (51) is interposed between an energizing laser (e.g., a diode laser (49)) and a single mode fiber active medium (43). In a preferred embodiment the single mode fiber active medium is surrounded by a multimode cladding (45) coupled to the multimode fiber. The source may serve as a pump laser for a fiber amplifier (30) or as an amplified spontaneous emission source. Arrangements for coupling several energizing lasers to the active medium are also described.
其他摘要	在光纤光源中，多模光纤（51）的一部分插在激励激光器（例如，二极管激光器（49））和单模光纤有源介质（43）之间。在优选实施例中，单模光纤有源介质被耦合到多模光纤的多模包层（45）包围。光源可以用作光纤放大器（30）的泵浦激光器或放大的自发发射源。还描述了用于将若干激励激光耦合到有源介质的布置。
主权项	An optical fiber amplifier (30) comprising an optical fiber (16) for providing gain to an input optical signal (λ s) thereon when said fiber is supplied with an optical pump signal (λ P1), and a source (1) of said pump signal characterized in that said source comprises a resonator including a single mode fiber gain section (43) capable of lasing at the wavelength of said pump signal, laser means (49) for energizing said gain section, and a first multimode fiber section (51) for coupling said laser means to said gain section.
