摘要： The beam path [80] of a laser source [10] is first pre-aligned to a predetermined reference, and then the optical axis [90] of the beam delivery system [40, 50] of a laser material processing platform [20] is pre-aligned to the pre-aligned beam path of the laser source such that the two coincide. If the laser beam [80] is invisible, a laser simulator [72] having a visible pre-aligned beam may be used instead. When every laser source and every laser material processing platform [20] in a predetermined population thereof are pre-aligned in this manner, then any one of the laser sources and any one of the laser material processing platforms in the population may be interchanged for any one of its kind in the population and interfaced with any one of the other kind in the population to form a laser material processing system without any additional alignment requirement during or after the interfacing operation and the laser beam paths [80] and beam delivery system optical axes [90] will be automatically aligned with each other after any laser source in the line is combined with any laser material processing platform in the line.

摘要： A computer controlled laser material processing system has a plurality of laser sources the beams of which are selectively operable between two modes. In a first raster engraving mode the beams are separated and independently controllable in synchronism with the motions of a beam delivery system to form plural, parallel, spaced apart scan lines on the surface of the workpiece for affecting the surface at high speed. In a second vector cutting mode the beams are combined such that they are collinear and have a power approximately equal to the sum of the powers of each individual laser source for cutting the surface at high power. The system may be switched by moving an optical element which, in the vector mode position, combines the beams and, in the raster mode position, separates the beams by either incrementally adjustably controlling the beams to provide a predetermined pitch between the scanned lines or by fixedly establishing a predetermined angle between the beams coupled with scanning in a variable interleaved pattern to achieve the desired pitch and image quality. Alternatively, an optical element may be inserted in the path of the collinear beams to separate them into parallel or angled beams for use in multi line scanning in the raster mode. The reverse sequence is followed to switch from raster to vector mode.

摘要： A portable laser processing module is adapted to be quickly and easily independently interfaced between a stationary exhaust docking station for fume extraction during in-office use and a portable air processing module for fume extraction during field use. A passageway in the housing connects the work area to an exhaust port which communicates with an inlet port in the docking station or the portable air processing module and ultimately to a blower unit in a facility or in an internal compartment in the portable air processing module which maintains a negative pressure in the work area for removal of fumes, debris, particulates, and contaminants therefrom. Guides are receivable in recesses between the laser processing module and the docking station or portable air processing module for guiding the module thereon, and a gasket seals the exhaust port and inlet port when the module is supported on the docking station or the portable air processing unit. A filtration unit including a filter set may be housed internally of the portable air processing unit.
