High power laser - optical fiber connection system

摘要

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.
