Abstract
One exciting application of nonlinear optical phase conjugation is to achieve real-time compensation for atmospheric turbulence. In atmospheric compensation, however, the power returning from even a retroreflector decreases rapidly (as 1/R2-1/R4) with increasing range, and can be extremely weak for ranges of interest (>~1 km). Previous work1,2 with nonlinear optical compensation of the atmosphere has consequently used threshold less phase conjugators. These usually require external pumps and a great deal of complexity.
