Abstract

Investigations of self-pumped phase conjugation (SPPC) of a low power cw-Ar-laser by using a dye-doped nematic liquid crystal are reported. The phase conjugated signal was generated by stimulated thermal scattering. The threshold power at a wavelength of 514.5 nm was about 30 mW and the maximum power-reflectivity was up to 1%. The ability to compensate phase aberrations has been demonstrated.
