Abstract:
A laser material processing platform comprising:a housing for supporting a workpiece; a beam delivery system having an optical axis along which a working laser beam is deliverable to the workpiece; a combiner mounted on said platform for combining plural laser beams incident thereon; a first mounting member on said platform for mounting a first laser to produce a first laser beam, said first mounting member precisely aligning the first laser such that the first laser beam is incident on said combiner along a first predefined beam path; and a second mounting member on said platform for mounting a second laser to produce a second laser beam, said second mounting member precisely aligning the second laser such that the second laser beam is incident on said combiner along a second predefined beam path, wherein said combiner is constructed to combine any laser beam incident thereon along said first beam path with any laser beam incident thereon along said second beam path into a combined laser beam that is output from said combiner as the working laser beam along said optical axis, whereby the first and second laser beams are made collinear and incident on the workpiece without substantial adjustment of said combiner.
