Why Light Beams Follow Curved Paths in Photorefractive Phase Conjugators,
Abstract
In recent years a variety of photorefractive phase conjugators have been demonstrated that rely on stimulated light beams. These self-pumped and mutually-pumped phase conjugators are all closely related and differ only in the number and angle of their input beams. Here we propose a detailed though necessarily simplistic description of how light beams spring up inside a photorefractive crystal, and why under some conditions these stimulated light beams appear to follow curved paths inside the crystal. We show that these curves are composed of a number of straight line segments which spring up by stimulated scattering in the photorefractive crystal.
