当用５１４.５ｎｍＡｒ＋激光束入射到掺Ｃｕ的ＫＮＳＢＮ晶体中时，观察到典型的猫型自泵浦相位共轭，而当用５１４.５和４８８ｎｍＡｒ＋激光束共线入射到该晶体中时，观察到自泵浦相位共轭猝灭现象．对这一现象给出了一个理论解释When a ５１４.５ｎｍＡｒ＋ laser beam was incident on a Cu-doped ＫＮＳＢＮ crystal, a cat type of self-pumped phase conjugation was observed. And when two collinear ５１４.５ and ４８８ｎｍ beams of Ａｒ＋ laser were incident on the crystal simultaneously, a phenomenon of self-pumped phase conjugation quenching was observed. Both theoretical and experimental results are presented and discussed.
