中文摘要：
研究了强光导引的弱光呼吸子传输问题.尽管弱光本身的非线性效应可以忽略,但强光通过强非局域非线性效应会对弱光形成约束并与弱光本身的衍射效应达到动态平衡,从而形成呼吸子.得到了弱光呼吸子的解析表达式,在此基础上分析了其束宽的呼吸演化规律,并对弱光呼吸子整体轨迹的形状、方位、旋向等性质进行了系统的研究.
英文摘要：
Breather for weak beam induced by strong beam in a strongly nonlocal nonlinear medium is investigated. Although the nonlinear-ity induced by the weak beam is weak enough to be negligible, the nonlinearity induced by the strong beam can balance the diffraction of the weak beam, thus the breather for weak beam comes into being. The analytical solution of the breather for weak beam is obtained. Based on the analytical solution, the evolution of the beam width is analysed, and the form as well as the direction of helix for the trajectory of the breather is systematically investigated.
