摘要
利用掺Co:(KNa)_(0.2)(Sr_(0.75)Ba_(0.25))_(0.9)Nb_2O_6晶体实现了无外场,无外反射镜、无外加泵浦光束的自泵浦连续波相位共轭,其相位共轭反射率达到40%,阈值功率小于0.02W/cm^2,首次利用此晶体以梯形切割实现了光折变晶体单区域四波混频相互作用产生自泵浦位相共轭波.
Self-pumped phase conjugate in Co-doped (K0.5Na)0.2(Sr0.75Ba0.25)0.9Nb2O6 crystal was demonstrated without external reflection mirrors, pumping beam and applied field. Its phase conjugation reflectivities as high as 40% were measured. The threshold power was lower than 0.02 W/cm2, The device operated by one-region four-wave mixing using the photorefractive effect with the trapezoid-cut crystal,
