This review introduced the properties and generation methods for creating phase conjugate images in non-linear materials. Particular emphasis was made on phase conjugation in photorefractive materials but parallels were drawn with other mechanisms such as stimulated Brillouin scattering. The advantages of phase conjugation within optical systems, such as aberration correction, amplification and phase locking, were illustrated with particular optical systems. In conclusion, new methods of self-pumped phase conjugation in non-Brillouin active and non-photorefractive media were described. This will offer the prospect of high speed phase conjugation at moderate powers and over a wide range of wavelengths. Such advances would lead to the commercial viability of optical systems that embody the principle of phase conjugation.
