摘要
实验研究了在一定条件下LiNbO3:Fe晶体中从自散焦到等效“自聚焦”转换的动态行为 ,提出了出现自聚焦的物理机理为双相位共轭的法布里 珀罗干涉腔中的多光束干涉与光折变效应的共同结果 .
We experimentally studied the dynamic behavior of conversion from self-defocusing to equivalent 'self-focusing' in LiNbO3:Fe crystal under certain experiment conditions. Its physical mechanism is the consequence of both the double-Phase conjugate Fabry-Perot interference cavity and photorefractive effect. It is possible to form bright spatial solitons in self-defocusing medium by the effect of dynamic conversion.
