A laser beam trimming and redirecting device having an aperture therein, the aperture defined by a inner beveled surface for focusing the laser beam directed therethrough and the aperture having an outer beveled surface, or beveled edge, for trimming the laser beam and reflecting the excess energy back towards a source at an angle other than 180 degrees. A reflection capture device positionable upstream of the trimming and redirecting device is configured to absorb the reflected energy instead of the laser beam source or delivery components. The capture device is a liquid cooled device so as dissipate the heat energy absorbed preventing degradation of the device.

Laser beam diverting aperture and reflection capture device

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.
