摘要：

Photorefractive bridge phase conjugation is studied theoretically by two-region coupled-wave theory. The dependence of phase conjugate reflectivity and transmissivity on the input intensity ratio is measured. When two incoherent beams symmetrically enter opposite Tb: Cu: KNSBN crystal faces, the maximum reflectivities are higher than 351%, 236% and 147% for incident angles of 17.5degrees, 27.5 and 39degrees respectively; we also obtain a transmissivity higher than 58% for an incident angle of 33.5degrees. A comparison between the experimental data and theoretical results is also given.
