Abstract
Laser scribing can be performed on a workpiece (104) such as substrates with layers formed thereon for use in a solar panel without need to rotate the workpiece (104) during the scribing process. A series of lasers (602, 622) can be used to concurrently remove material from multiple positions on the workpiece (104). Each laser (602, 622) can have at least one scanning device (614, 630, 632) positioned along a beam path thereof in order to adjust a position of the laser output relative to the workpiece (104). By adjusting the beam or pulse positions using the scanning devices (614, 630, 632) while translating the workpiece (104), substantially any pattern can be scribed into at least one layer of the workpiece (104) without the need for any rotation of the workpiece (104).
