摘要： An optical scan system welds or marks a part by directing an optical beam onto the part at a sufficient energy density level to weld or mark it. A method of controlling a pattern where the part is to be exposed to the beam at the sufficient energy density level includes disposing a waveguide between the part and an optical source of the optical scan system to prevent areas of the part that are not to be welded or marked from being exposed to the beam at the sufficient energy density level to weld or mark them, allowing the areas to be welded or marked to be exposed to the beam at the sufficient energy level. In an aspect, the waveguide prevents the beam from being reflected in an undesired direction. In an aspect, the waveguide redirects the beam from the areas of the part that are not to be welded or marked to areas that are to be welded or marked to concentrate the energy on the areas to be welded or marked. In an aspect, a dissipative waveguide dissipates energy of the beam in the areas of the part that are not to be welded or marked so that those areas are not exposed to the beam at the sufficient energy density level.

摘要： Unabsorbed infrared laser light that has passed though plastic parts to be welded with a low absorption TTIr process is recirculated back to the low absorption weld interface for reabsorption in the process. A beam of infrared laser light is directed at the plastic parts to be welded, a transmissive first part and an absorptive (or partially absorptive) second part. The infrared laser light impinges the transmissive part and first transits through the transmissive part to be welded to a weld interface at the junction of the two parts. At the weld interface, either the infrared laser light is partially absorbed by an additive infrared absorber, the infrared laser light is partially absorbed by the absorptive part, or both. The portion of the infrared laser light that is not absorbed continues through the absorptive part and exits the far side. This infrared laser light is then redirected back to the weld interface. On the second pass (and any subsequent passes thereafter), more infrared laser light is absorbed in the partially absorbing medium (the additive infrared absorber, the absorptive part, or both). In an aspect, the parts are tubular parts with the transmissive part coaxially surrounding the absorptive part. The infrared laser light is redirected with a cylindrical mirror that coaxially surrounds the tubular parts. In an aspect, the parts include a tubular part and a fitting and the infrared laser is redirected with a spherical mirror that surrounds the parts.
