| 英文摘要 | A laser system can include an optical fiber having a spatial filter defined as a core extension coupled to or integrally formed in an optical fiber so as to reduce the coupling of optical radiation into a fiber cladding. Such a core extension can be formed by removing a length of the cladding from the optical fiber, leaving a portion of the core exposed at the end of the fiber. Alternatively, a core extension can be formed by coupling an end cap to the core of the optical fiber at a fiber end surface. By selecting a length of the core extension based on a beam divergence and beam diameter, radiation coupling into the fiber core can be reduced. |
