Abstract

A method of stabilizing the phase conjugate wave front generated by BSO crystal is proposed. First the fluctuation properties are examined by means of cross-correlation and power-spectrum analysis. Then a negative feedback loop, which includes the field applied to the crystal and the conjugate wave-front detection at a small part of the crystal, is constructed to stabilize the intensity of the desired wave front. The results show almost complete elimination of the fluctuation.
