Multiline phase conjugation in resonant materials.
We present a direct experimental demonstration of multiwavelength phase conjugation through degenerate four-wave mixing. The experiments were performed using a multiline CO2 TEA laser with SF6 as the nonlinear medium. Using a vidicon to observe the signal in the far field, we show good aberration-correction ability. A qualitative description of the additional cross coupling is also provided.
