摘要:We show that Cu ions doped in (KxNa1-x)0.4(SrBa1-y)0.8Nb2O6 (KNSBN) form two energy levels in the band gap, which increase the effective charge-combination-center concentration N(eff). The two-wave coupling gain and the response speed of KNSBN crystals are increased while the photoconductivity and the effects of a dc field on the photorefractive properties are reduced. Self-pumped phase conjugation (SPPC) experiments have revealed that the effects of Cu ions on the photorefractive properties have a wavelength dependence. The SPPC response time at the e-1 level can be shortened to 200 ms.
