Abstract
A laser welding system includes a free-spacing beam delivery laser head having a linear array of at least two laser diodes. Each of the diodes generates a laser beam of a predetermined wavelength and spectral width, the laser beams adapted to weld a workpiece having a first component and at least one other component to be welded to the first component, the first component being substantially transmissive to the wavelength, the other component being substantially absorptive of the wavelength. A lens is spaced a predetermined distance from each of the laser diodes, each of the lenses adapted to focus the respective laser beam into a focused laser beam segment, thereby forming a continuous line of laser energy from a substantially serial combination of each focused laser beam segment. The continuous line of laser energy is in a plane containing the workpiece, and is substantially orthogonal to the workpiece translation direction.
