phase conjugation

The use of a reflective device, which can be fashioned from a variety of materials including gases, solids, dyes, aerosols, semiconductor crystals and plasmas, to replicate a laser beam by reversing the spatially dependent characteristics of its electrical field, and thus can cancel aberrations introduced into the beam after it leaves its source. Often called wavefront reversal. Nonlinear optical interactions such as three-wave and four-wave mixing, stimulated Brillouin scattering, stimulated Raman scattering and photon echoes have been used to produce conjugate waves. Two classes are thought to be important operationally: those requiring laser beams in addition to the beam whose phase-conjugate replica is sought, and self-pumped conjugators that do not require additional beams.
