摘要：
In this paper, we reported our experimental observations of the special scattered light inLiNbO(3) : Fe crystal. We studied the far-field scattering light of five kinds of configurations, respectively, when the angle between the direction of the c axis of the crystal and the direction of the incident long linear beam is 0 degrees,30 degrees, 45 degrees, 60 degrees, 90 degrees. We observed an interesting phenomenon firstly that strong light scattering appeared along the direction of the incident long linear beam on the crystal, and the scattering light is constituted of the filaments that perpendicular to the direction of the incident beam on the crystal in each situation. We also observed a new phenomenon that the scattering light appear perpendicular to the direction of the incident beam when the angle is 90 degrees. (C) 2017 Elsevier GmbH. All rights reserved.
