Abstract
An apparatus that divides a single laser beam into two or more beams that can be directed at an object, such as a work piece, to perform laser heat treatment is disclosed. An adapter stage is in optical communication with a light source, such as a laser source, and arranged to receive a light beam from the light source. A focus stage in optical communication with the adapter stage is arranged to receive the light beam from the adapter stage and to focus the light beam. A beam splitting stage in optical communication with the focus stage is arranged to receive the focused light beam and to split the focused light beam into a multiple light beams. A redirection stage in optical communication with the beam splitting stage is arranged to receive the multiple light beams and to direct them toward a plurality of target locations on the object.
