| 摘 要： | 基于CCD图像采集技术与计算机软件处理技术，提出了空间光孤子的顶侧面观测法.此方法能够非常直观地显示出光孤子在晶体内部传输时，在水平及垂直方向上不同位置的轮廓图.用这种方法观测到了KNSBN晶体中的二维光伏明孤子，观测结果与理论模拟结果相一致.

| Abstract: | Basing on CCD technology and software processing, a new method, namely top- and side-view method, is presented for the observation of spatial optical solitons in photorefractive crystals. When a laser beam is propagating in a crystal, this method has an ability to show the horizontal and vertical outline of the beam at any location of the crystal very intuitively. By use of this method, we have experimentally observed the two-dimension bright photovoltaic solitons in a KNSBN crystal, and the measured results are qualitatively in agreement with the results of numerical simulation. |
