| 摘 要： | 利用变分法对傍轴椭圆高斯光束在耗散的并具有椭圆对称响应的强非局域克尔介质中的传输特性进行了研究，得到了光束各参量所满足的演化方程．结果表明：当损耗足够小时，不同入射功率情况下椭圆高斯光束的长、短轴分别作不同周期、不同幅度的周期振荡，并总体呈现展宽趋势．

| Abstract: | By employing a variational approach, the propagation of elliptically Gaussian beams in lossy strongly nonlocal Kerr medium with elliptically symmetric response is discussed and a set of full-parameter evolution equations for the beam are obtained. The results show that the long and short axis of the elliptically Gaussian beam will experience periodic oscillation with different periods and intensities in the case of different input power and tend to expand as a whole. |
