【摘要】 利用 Cu∶KNSBN晶体 ,研究了在两束泵浦光对称入射的条件下 ,自泵浦与互泵浦相位共轭共存时相互竞争和相互影响的特性 ,以及共存时的相位共轭特性与两束泵浦光的入射位置、入射夹角和泵浦比之间的关系 ,并对自泵浦相位共轭反射率和两束泵浦光共同存在条件下的自泵浦相位共轭反射率进行了比较更多还原

【Abstract】 The phase conjugation properties of Cu∶KNSBN crystal with two symmetrical incident beams are investigated when self pumped phase conjugation (SPPC) and mutually pumped phase conjugation (MPPC) coexist.The dependences of phase conjugation properties on incident position,incident angle and beams ratio are given.Also SPPC properties when SPPC and MPPC coexist are compared with those when SPPC exists alone.更多还原
