摘　　要：通过对KNSBN:Cu光折变晶体的自泵浦相位共轭(SPPC)和诱导自泵浦相位共轭(ISPPC)特性的研究,分别利用SPPC和ISPPC实现了XOR逻辑操作和AND逻辑操作,并将SPPC和ISPPC有机组合实现了全光型半加器逻辑操作。The properties of self-pumped phase conjugation (SPPC) and induced self-pumped phase conjugation (ISPPC) of KNSBN: Cu crystals were studied. XOR and AND logic operations were realized with SPPC and ISPPC. The all-optical half-adder logic operation was accomplished with SPPC and ISPPC. The phase conjugation reflectivity of the sum bit is 69%, and the velocity response is about several seconds.
