We present the first report to the best of our knowledge of highly eff
icient phase conjugation in a laser-pumped polymer-dye saturable ampli
fier. Phase-conjugate reflectivity of as much as 210% at 560 nm has be
en obtained. Moreover, efficient reflectivity has been obtained in the
broad wavelength region from 556 to 567 nm. (C) 1998 Optical Society
