ABSTRACT:
A compensator/remapper and method for compensation and remapping of a laser beam for control and correction of laser pointing and thermal drift instability in a laser beam delivery system including a laser generating a laser beam and a plurality of optical elements for directing, shaping and focusing the laser beam along a beam path to a target. A compensator/remapper includes a compensator element and a remapper element. The compensator element receives an input laser beam having a range of input angles and lateral displacements and redirects components of the input laser beam into an aligned laser beam having evenly distributed and parallel components. The remapper element is illuminated by the aligned laser beam from the compensator element and remaps the components of the aligned laser beam into a shaped laser beam having a profile that is optimum for remapping into a flat top laser beam.
