Abstract
Phase conjugation based on four wave mixing (4WM) in nonlinear materials is of great interest for dynamic correction of intracavity phase aberrations in Nd-YAG lasers. For pulsc laser operation the phase conjugation is usually performed in bulky gas or liquid cells using stimulated Brillouin scattering. However, due to the progress of the laser technology it is now required to investigate new solid-state phase conjugate mirrors which exhibit high reflectivity and fidelity. For this purpose we will present and discuss two types of nonlinear mirrors - first, the IR sensitive Rb doped BaTiO, crystal, second the flash (or diode) pumped Nd-YAG (or Nd-YVO) gain media.
