Diffraction-free beams are generated by the use of diffractive optical elements written on a spatial light modulator (SLM). By alteration of the pattern placed on the SLM, the axis of propagation can be both shifted laterally and rotated. We present experimental results obtained by use of a magneto-optic SLM.
无衍射光束是通过使用写在空间光调制器（SLM）上的衍射光学元件产生的。通过改变放置在SLM上的图案，传播轴可以在横向移动和旋转。我们展示了使用磁光SLM获得的实验结果。
