摘要

摘要: 为了得到低振幅双光子屏蔽光伏孤子时间特性的结果，采用数值模拟的方法对低振幅双光子屏蔽光伏孤子的时间特性进行了理论分析，得到了明和暗孤子时间特性的演化方程。结果表明：孤子的宽度随时间的演化单调递减到一个最小值直至稳态孤子的形成，在相同的演化时间内，孤子的半峰全宽随着孤子峰值强度和暗辐射比值的增大而变窄。

Abstract: In order to obtain the time-dependent behavior of one-dimensional two-photon screening-photovoltaic spatial solitons under low-amplitude conditions, the time-dependent behavior of one-dimensional two-photon screening-photovoltaic spatial solitons under low-amplitude conditions is presented theoretically. The time-dependent propagation equations of quasi-state bright and dark two-photon screening-photovoltaic solitons are obtained by numerical method. The results indicate that as time evolves, the intensity width of screening-photovoltaic spatial solitons decreases monotonously to a minimum value toward steady state. The higher the ratio of soliton peak intensity to the dark irradiation intensity is, the shorter the FWHM of photovoltaic solitons within propagation time will be.
