Abstract
We present experiments demonstrating reciprocity for conjugation of hi ghly scattered light; if a fraction eta of the total scattered light i s incident on a phase-conjugate mirror having reflectivity rho, then a fraction rho eta(2) returns back through the scatterer as a phase-con jugate wave, with the remaining fraction rho (eta - eta(2)) being lost due to scattering. Low efficiency results from inability to gather a large fraction of scattering, but the efficiency is higher than is pos sible without conjugation.
