Self-pumped Phase Conjugation of Co-Doped (KNa)0.1( Sr0.75Ba0.25)0.9Nb2O6 Crystal
-
Abstract
Self-pumped phase conjugate in trapezoid-cut Co-doped (KNa)0.1( Sr0.75Ba0.25)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.
