An apparatus includes a laser system that includes a first fiber having an output end and situated to propagate a first laser beam with a first beam parameter product (bpp) and a second fiber having an input end spliced to the output end of the first fiber at a fiber splice so as to receive the first laser beam and to form a second laser beam having a second bpp that is greater than the first bpp, wherein the output end of the first fiber and the input end of the second fiber are spliced at a tilt angle so as to increase the first bpp to the second bpp.

Beam parameter product (BPP) control by varying fiber-to-fiber angle

An apparatus includes a camera, a dark field illumination source, and a fiber inspection housing including a fiber connector input situated to receive an optical fiber connector so that an optical fiber output end of the optical fiber connector is removably insertable into an interior region of the fiber inspection housing and securable at a predetermined location in the interior region, a camera input situated to receive and secure the camera so that the camera is in optical communication with the interior region and the optical fiber output end, and a dark field illumination source input situated to receive the dark field illumination source so that light emitted from the dark field illumination source is received by the optical fiber output end at a dark field illumination angle and is scattered by contamination or defects associated with the optical fiber output end so as to be detectable by the camera.
