Hologram production technique

A system for forming interference patterns on the surface of a workpiece, the system comprising:

• a laser generating a laser beam;
• a beam splitter dividing the laser beam into a first laser beam and a second laser beam;
• a controller providing as output at least one control signal;
• and
• at least one beam deflector receptive of the first and second laser beams guiding the first and second laser beams along different paths to a prescribed pixel location on the surface of the workpiece, thereby combining the first and second laser beams at a prescribed azimuthal direction and included angle;
• wherein at least one beam deflector is receptive of the at least one control signal thereby controllably deflecting at least one of the first laser beam and the second laser beam to the prescribed pixel location.

A method of ablating a workpiece, the method comprising:

• generating a laser beam;
• dividing the laser beam into a first laser beam and a second laser beam;
• and
• controllably guiding the first and second laser beams along different paths to a prescribed pixel location on the surface of the workpiece by rotating about at least one axis at least one beam deflector receptive of the first and second laser beams, thereby combining the first and second laser beams at a prescribed azimuthal direction and included angle.
