Abstract:
An active optical system for beam-steering an incoming laser beam, comprising:a) a first control optics assembly for receiving an incoming laser beam and adjusting that incoming laser beam in accordance with first desired wavelength, polarization and beam propagation parameters; b) a driver element for producing a driver laser beam; c) a second control optics assembly for receiving said driver laser beam and adjusting that driver laser beam in accordance with second desired wavelength, polarization and beam propagation parameters; d) a second order non-linear optical element (SONOE) for receiving an output from the first control optics assembly and an output from the second control optics assembly, said SONOE providing a non-linear optical interaction between said outputs such that a propagation direction modified laser beam is provided that propagates at a different angle than the incoming laser beam and at a difference wavelength thereof; e) egressing optics for receiving said propagation direction modified laser beam and adjusting that laser beam in accordance with desired wavelength, polarization, and beam propagation parameters, the output of the egressing optics having the laser beam propagation direction shifted relative to the incoming laser beam direction.
