Abstract:
A multi-stage laser beam despeckling device including a first laser beam despeckling module for optically multiplexing an input laser beam into a temporal/spatial coherence-reduced output laser beam; and a second laser beam despeckling module, optically coupled to the first laser beam despeckling module, for receiving the temporal/spatial coherence-reduced as an input laser beam to the second despeckling module and producing a further temporal/spatial coherence-reduced output laser beam.
