The stimulated Brillouin scattering optical amplifier includes a first control
optics assembly, a driver element, a second control optics assembly, a Brillouin
active medium, and egressing optics. The first control optics assembly receives
an incoming laser beam and adjusts that incoming laser beam in accordance with
first desired wavelength, polarization and beam propagation parameters. A driver
element produces a driver laser beam. A second control optics assembly receives
the driver laser beam and adjusts that driver laser beam in accordance with second
desired wavelength, polarization and beam propagation parameters. A Brillouin active
medium receives an output from the first control optics assembly and an output
from the second control optics assembly. The Brillouin active medium provides a
non-linear optical interaction between the outputs such that the incoming laser
beam is amplified producing an amplified Brillouin active medium output laser beam
and a depleted driver laser beam. Egressing optics receives the amplified Brillouin
active medium output laser beam and the depleted driver laser beam. The egressing
optics controllably transmits the amplified Brillouin active medium output laser
beam in accordance with third desired wavelength, polarization, and beam propagation
parameters and prevents transmission of the depleted driver laser beam. The output
of the egressing optics includes an amplified egressing optics output laser beam.
