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.
