Abstract
A diffractive optical element (DOE) is included in an apparatus for combining a plurality of laser beams. The DOE combines the plurality of laser beams to generate a plurality of spatially distributed laser beams. The DOE is one of movable or stationary. The spatially distributed laser beams are usable to pattern a workpiece.
Claims22
An optical system comprising:
- a diffractive optical element (DOE) configured to generate spatially distributed laser beams in at least one plane based on a plurality of laser beams impinging on the DOE.
A method for combining electromagnetic radiation from multiple light sources, the method comprising:
- generating, by a diffractive optical element (DOE), spatially distributed laser beams in at least one plane based on a plurality of laser beams impinging on the DOE.
