Ring self-pumped phase conjugation of Ce-doped KNSBN crystals
Self-pumped phase conjugation in a-face titled-cut Ce-doped (KNa)0.1(Sr0.75Ba0.25)0.9Nb2O6 crystal was demonstrated without external reflection mirrors, pumping beam and applied field, and phase conjugation reflectivities as high as 25% were measured. The threshold power was lower than 0.03 W/cm2. Its photorefractive coupling constant was computed for various a-face titled-cut angles for the first time.
