【摘要】 在实验制备铌酸锶钡钾掺Ｍｎ晶体样品（ＫＮＳＢＮ：Ｍｎ）上，实现了Ｈｅ－Ｎｅ激光波长的自泵浦相位共轭，测得ＫＮＳＢＮ：Ｍｎ晶体的自泵浦相位共轭反射率高达７０％，研究了自泵浦相位共轭反射率随入射光束角度、功率密度的关系，测量了自泵浦相位共轭反射率随激光功率密度的变化。更多还原

【Abstract】 The Mn-doped（KNa）_0.1 (Sr_0.6Ba_0.4)_0.9Nb₂O₆（KNSBN）crystals grown,poledand polished in this experiment were discribed. The self-pumped phase conjugation ofMn-doped KNSBN was observed at 632.8nm using He-Ne laser. The self-pumped phaseconjugation reflectivity as high as 70%was measured. The reflectivity as function of theincident angles and the incident intensities as well as the relation of the response time tothe incident intensities were studied experimentally。更多还原
