A method for shaping a laser beam for cutting a stent pattern into a stent, comprising:
- providing a laser beam having a first intensity distribution;
- and
- re-mapping the first intensity distribution of the laser beam to a second intensity distribution.
A method for cutting a stent pattern into a tube, comprising:
- remapping the intensity distribution of a laser beam to a non-Gaussian intensity distribution;
- and
- applying the non-Gaussian intensity beam to a tube to remove at least a portion of a wall thickness of the tube.
