Self‐pumped phase conjugate in trapezoid‐cut Ce‐doped KNa(Sr0.61Ba0.39)0.9Nb2O6 crystal was demonstrated without external reflection mirrors and applied field, phase conjugation reflectivities as high as 25% were measured. The threshold power was lower than 0.03 W/cm2. The device operated by one‐region four‐wave mixing using the photorefractive effect.
