ABSTRACT:
At the receiving end or point at which a data or information carrying seed laser beam is to be received after traveling through a medium, a pump laser beam is propagated through the medium to the sending end of the medium at which point the now aberrated pump laser beam may be amplified if necessary and directed to and propagated through a waveguide composed of a suitable third order optically nonlinear medium. The data carrying seed laser beam is directed to and through the waveguide where it is phase conjugated and then through the medium in the direction opposite to that of the pump laser and arrives at the receiving end as an unaberrated laser beam. The data carrying laser beam and the pump laser beam have a frequency difference equal to the Stokes frequency shift of the waveguide material.
