Abstract: A laser-optical fiber tuning and control system which optimizes coupling of a laser output into an optical fiber by minimizing the amount of light scattered into the fiber cladding, which provides a realtime indication of whether the radiation reaches the output end of the fiber to an emergency shut-down switch, and which provides a communications system for control of the laser from the output end of the optical fiber.

Abstract: A system for coupling laser radiation at a high power to an optical fiber while dissipating heat from scattered laser and optical pump radiation, including an optical fiber, a protective ferrule surrounding a portion of the optical fiber extending from the input face of the optical fiber and welded to the fiber in the region of the input face and otherwise separated from the fiber by an air space, and a holder surrounding the ferrule to absorb scattered radiation and dissipate heat.
