Fresnel reflection termination system for high powered laser systems
Abstract
A fresnel reflection termination system includes a laser source, a folding mirror to reflect a laser beam, a focusing lens to focus the laser beam on the folding mirror, and a laser beam dump. The laser beam dump has an outer absorption surface for absorbing fresnel reflections, an inner termination area for capturing fresnel reflections, and a cooling mechanism within the inner termination area for dissipating heat generated by the captured fresnel reflections. The system terminates fresnel reflections to prevent costly damage to the environment or hardware surrounding the system.
