Abstract
A dual-beam laser cutting system uses laser beam polarization to output two identical laser beams. The dual identical laser beams are spaced appropriately to simultaneously cut a water thus increasing the laser cutting system's throughput as compared to a single-laser cutting system. In one implementation, the dual-beam laser cutting systemutilizes a beam expander, two half-wave plates, a polarizing beam splitter, a mirror, and two lensesto provide two identical laser beamsfrom a single laser source. The identical laser beamsare tuned to have the same power, cross-sectional diameter, and polarization direction. One of the half-wave platesis rotated to yield laser beams with the same power. The other half-wave plateis rotated to yield laser beams with the same polarization direction.
