| 摘 要： | 通过数值模拟研究了非线性腔的横向效应，非线性表现在光场通过放大介质时所引起的相位变化与强度有关，模拟结果显示，随着非线性系数的变化，腔中的光场分布表现丰富的时空不稳定行为，其中包括横模跳变，时空周期行为以及光学涡旋的出现。

| Abstract: | The transverse- effect of a light field in a nonlinear- cavity is studied by numerical simulation. The nonlinearity behaved the phase variation being related to light intensity as it passing through an amplification medium. The results shows that when the nonlinear coefficient is changed, the ditribution of light field in the cavity exhibits various spatiotemporal instabilities, such as the transitions of transverse modes, periodical spatiotemporal phenomena and optical vortices. |
