摘　　要：从理论和实验两方面研究了非局域光孤子在热致非线性铅玻璃材料中的偏转现象.理论上,利用保角变换的方法,求出了材料的响应函数,讨论了边界对响应函数的影响,得到了偏离中心入射时孤子中心传输的轨迹方程.实验上,观察了光孤子在矩形边界铅玻璃材料中偏转.理论结果和实验结果符合得比较好.We studied the steering of the nonlocal spatical optical soliton in thermal optical nonlinear lead glass theoretically and experimentally. By employing the conformal mapping method, the response function of the lead glass was obtained, and the influence of the boundary on the response function is discussed. Then we obtained the trajectory for the off-center soliton and the output displacement equation when the point of incidence is varied. We also observed experimentally the phenomenon of steering of the optical soliton in lead glass whose boundary shape is rectangular. The theoretical results are in good agreement with the experimental observations.
