Abstract
A stack of parallel but laterally separated laser beams emitted from a pair of laterally separated laser diode bars are focused into a single vertical plane through the use of an interleaved array of stacked, angular glass plates. Successive plates oppositely refract laser beams from successive radiating levels of the stacks of laser bars so that beams emerging from the glass plates lie in the same vertical plane, thereby overcoming the lateral displacement among beams emerging from the laser bars.
