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.

摘要： A system for homogenizing the intensity profile of light includes a plurality of fiber coupled light sources for emitting fiber output beams from fiber output ends, and a light pipe optically coupled to the fiber output beams for producing a uniform light pipe output beam, an interleaver that transmits a first set of fiber output beams and reflects a second set of fiber output beams so that the principal rays of the fiber output beams propagate in a common plane, a first optical element for converging the principal rays, and a second optical element for telecentrically imaging the beams into the light pipe such that the principal rays of the beams propagate parallel to each other and the beams are focused in the light pipe in a focal plane transverse to the direction of propagation.

摘要： An intensity distribution management system includes a light source, a mask for receiving light therefrom and for allowing some light to propagate through and past the mask, a surface for receiving light allowed past the mask, and a diffusive element disposed between the mask and the light source for ensuring a substantially even light intensity distribution in relation to the surface. An imaging method includes emitting a light beam, manipulating the beam to have a first numerical aperture across a first divergence axis, directing the beam through a diffusive element to increase the numerical aperture of the beam, directing the beam through one or more transmissive portions of a mask, the mask being disposed relative to the diffusive element, and imaging transmitted portions of the beam to a target surface wherein the beam has a substantially ripple-free and uniform intensity distribution across the first divergence axis at the target surface.
