Paper Abstract

Optical phase conjugation' has been extensively investigated due to its capability of generating a beam whose wavefront has an envelope proportional to the complex conjugate of another beam and which propagates in a direction opposite to the first one. Such beams are generated primarily by four-wave mixing processes 2 or by using deformable mirrors. In the latter method, some combination of a wave front sensor and a deformable mirror is used to imprint the spatial phase modulation obtained from the wavefront sensor onto the deformable mirror in a closed loop operation. The deformable mirror action can be achieved either by mechanical means3 (piezoelectric activation) or by refractive index modulation.4
