1. A system for piezoelectric-based beam stabilization, the system including:
a laser beam source configured to produce a laser beam;
a target;
a lens assembly including a lens objective configured to produce an output beam from the laser beam and at least one optical element movably coupled to the lens assembly and configured to direct the laser beam to the target; and
one or more piezoelectric transducers coupled to the at least one optical element and configured to dynamically reposition the at least one optical element in response to relative motion between the target and the lens assembly.
