Cu：KNSBN晶体中复色光自泵浦相位共轭猝灭实验及其理论解释

EXPERIMENT AND THEORY OF POLYCHROMATIC LASER BEAM SELF PUMPED PHASE CONJUGATION QUENCHING IN Cu DOPED KNSBN CRYSTALS

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．

When a 514 5nm Ar + 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.
