Embodiment Construction

[0034] In general, the present invention relates to the arrangement of optical fibers, in particular for the delivery of high power laser beams. Embodiments of the present invention relate to optical fibers, optical connectors, optical couplers, and fiber optic stub configurations for slowing and eliminating the deterministic effects of contaminants located outside the fiber core.

[0035] In general, therefore, an optical fiber can have a core, a cladding, and can have additional cladding, as well as coatings and other protective layers. For example, the optical fiber can be a hollow-core photonic crystal or a solid-core photonic crystal. Typically, an optical fiber cladding surrounds the core, a coating (if present) surrounds the cladding, and other protective layers (if present) surround the coating. The core typically has a circular cross-section, although other shapes, such as square, are also contemplated. In an embodiment, the optical fiber or a length of optical fibe...

Abstract

There is provided a multi-clad fiber assembly for reducing and eliminating deleterious laser-contaminant interrelations, and methods of making these assemblies. There is provided an optical connectorhaving contaminants that are shielded from causing detrimental thermal effects, during laser beam transmission, by preventing laser-contaminant interactions.

Description

[0001] This application claims the benefit of the filing date of U.S. Provisional Application No. 62 / 667,345, filed May 4, 2018, the entire disclosure of which is incorporated herein by reference. technical field [0002] The present invention relates to optical fibers, optical coupling to optical fibers, and optical fiber configurations that enhance coupling of light to optical fibers. Background technique [0003] Additive manufacturing systems based on infrared (IR) (for example, wavelengths greater than 700nm, especially wavelengths greater than 1000nm) suffer from, among other things, two disadvantages, which limit build volume and build speed. [0004] As used herein, unless expressly stated otherwise, "UV", "ultraviolet light", "UV spectrum" and "UV portion of the spectrum" and similar terms shall be given their broadest meaning and include wavelengths from about 10 nm to about 400nm and 10nm to 400nm light. [0005] As used herein, unless expressly stated otherwise,...
