Wavefront conjugation and amplification for optical communication through distorting media: experiment.
The laboratory performance of recently proposed new architectures for optical communication through distorting media is investigated. After phase-conjugating a weak beam with a mutually incoherent source a power amplification with a gain factor of 500 was demonstrated. The amplified beam can be employed for distortion-free optical communication by direct signal transmission. In a different configuration, wavefront matching applicable for coherent detection is proved to be feasible.
