Abstract
A laser fabrication method and a laser fabrication system. The laser fabrication system includes an ultrafast laser source configured to output a laser beam; and a digital micromirror device (DMD), configured to receive, shape, and scan the laser beam, wherein more than one binary holograms are synthesized to form a scanning hologram applied to the DMD. The shaped laser beam, containing one or multiple focal points, leaving the DMD, are focused to the sample for fast laser fabrication.
