Abstract
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.
