Abstract
A moving slab laser includes a slab carriage driven to-and-fro along a precise rectilinear reciprocal path by a liner motor under the control of a computer. The reciprocal motion of the slab is precisely guided by cross roller ways or ball bushing bearings to minimize non-rectilinear motion-dependent output beam steering effects. In one embodiment, the lasant slab is separated into a pair of axially spaced geometrically identical portions which are reciprocated in opposite directions to cancel motion direction dependent beam steering effects.
