Abstract
An optical bench for processing laser light in a laser system, including an optical bench housing, a beam dump mounted to the optical bench housing so as to be in optical communication therewith, steering optics mounted within the optical bench housing for directing the laser light in a path from a laser light input to an output, and a mechanism for causing the laser light to deviate from the path and be directed into the beam dump upon recognition of a specified condition in the laser system, wherein the laser light is thermally isolated from the steering optics. The mechanism can either cause at least one optically reflective element to be inserted into the path, cause at least one optical element of the steering optics to have a change in position with respect to the path, and/or causes at least one optical element of the steering optics to be removed from the path.
