Abstract
Official abstract text for this publication.
An improved high power spatial filter, system and method. In the system, an optical fiber is disposed inside a ferrule channel structure, and the channel structure is aligned with a focusing lens system. The end of the fiber is at a distance D from the channel opening that faces the focusing lens system, and D is determined by the system's numeric aperture factor and the cladding thickness of the optical fiber.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical system comprising: a focusing component configured to focus a beam incident thereon so that the focused beam includes a plurality of rays converging towards an axis at an angle range which is characterized by a small numerical aperture (NA) at most equal to a target NA, and another angle range characterized by a high NA at least equal to the target NA; an elongated ferrule extending along a longitudinal axis and having an inner surface defining…
