对傍轴椭圆高斯光束在具有椭圆对称响应特性的强非局域非线性介质中的演化规律进行研究,得到了光束各参量演化的精确解析解,分析了单向空间光孤子和强非局域椭圆空间光孤子的形成条件,发现了椭圆光孤子的相移与介质响应函数的椭圆率有关.
We investigate the propagation of the elliptical Gussian beam in strongly nonlocal nonlinear media with an elliptically symmetric response. We derive analytical formulas for the evolution of the beam parameters and conditions for the formation of nonlocal elliptical spatial optical soliton.
