Low-power phase conjugation based on stimulated Brillouin scattering in fiber amplifiers.
Phase-conjugating stimulated Brillouin scattering (SBS) mirrors are frequently used to improve the brightness of solid-state lasers. With a scheme for designing fiber amplifiers as SBS phase conjugators the power requirements can be decreased by orders of magnitude; yet only low coherence is required, and high fidelity is reached. A peak power of 5 W was demonstrated to be sufficient for optical SBS phase conjugation.
