Abstract
Official abstract text for this publication.
A method and apparatus for suppression of stimulated Brillouin scattering (SBS) includes a master oscillator (MO) that generates a beam; a birefringent element that receives and transmits the beam, wherein the beam is transmitted with a transmission delay between two orthogonal axes; a polarization controller that receives the beam and transmits the beam with a desired polarization; a fiber amplifier that receives the beam, amplifies the beam, and transmits a beam; a compensating birefringent element that receives the beam, approximately removes the transmission delay between the two axes of the beam, and transmits an output beam; and a polarization detector that detects the output beam's polarization and provides feedback to the polarization controller to ensure that the polarization of the output beam is approximately equal to a desired output polarization, so as to reduce SBS.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for reducing stimulated Brillouin scattering (SBS), comprising: a master oscillator (MO) configured to generate a beam; a birefringent element configured to receive the beam from the MO and to transmit the beam, wherein the beam is transmitted with a delay between two orthogonal axes; a polarization controller configured to receive the beam from the birefringent element and to transmit the beam with a desired polarization; a fiber amplifie…
