ABSTRACT:
An optical fiber assembly includes a clad optical fiber having an end-cap thereon. Radiation is focused into the optical fiber via the end-cap. A roughened portion of the fiber cladding behind the end-cap allows any radiation focused into the fiber and propagating in the cladding to escape the optical fiber. A concave reflector surrounding the optical fiber reflects the escaped radiation away from the fiber assembly. A connector for connecting the optical fiber to a laser includes an air-cooled beam-dump for receiving the radiation reflected away from the optical fiber.
