We report photorefractive passive phase conjugation of GaAlAs laser radiation at 815--865 nm and Ar/sup +/ laser radiation at 1090 nm. A ring passive phase conjugate mirror was used with BaTiO/sub 3/ as the real-time holographic gain medium. With GaAlAs lasers phase conjugate reflectivities of up to 16% uncorrected for Fresnel losses were recorded. Effects of the strong associated feedback to the laser and attempts at mode locking are described. At 1090 nm the reflectivity remains approximately the same, but with a significantly longer time constant.
