Abstract Self-pumped phase conjugate in trapezoid-cut Co-doped (KNa)_0.1( Sr_0.75Ba_0.25)_0.9Nb₂O₆ (Co-KNSBN) crystal was demonstrated without external reflection mirrors and applied field, phase conjugation reflectivities as high as 40.5% were measured. The threshold power was lower than 0.02 W/cm². The device was operated in one-region four-wave mixing using the photorefractive effect.
