ABSTRACT:
Laser materials processing apparatus for performing processing with a fiber optic transmitted beam is disclosed. A fiber injecting lens is selected to have a focal length of sufficient length to enable the use, for materials processing, of the diverging beam emitted at an output end of the fiber without the need for a beam focusing lens type output coupler.
