论文摘要
我们报告了光学龙卷风波（TOWS）的实验产生和操纵。通过控制自我关注的长度，总角动量和折叠的焦点偏差，可以操纵光拖的传播特性，尤其是其主强度裂片的角速度。我们实现了从0到1100度的强度裂片的累积旋转角度。另外，我们确认TOW在焦点碰撞情况周围获得了最高的角速度。我们的实验结果与数值结果非常吻合。
We report experimental generation and manipulation of optical tornado waves (ToWs). By controlling the self-focusing length, total angular momentum, and foci deviation of ToWs, the propagation properties of optical ToWs, especially their angular velocity of the main intensity lobes, can be manipulated. We achieve controlling the accumulated rotation angle of the intensity lobes from 0 to 1100 degrees. Also, we confirm that ToWs get the highest angular velocity around the foci coincide situation. Our experimental results are in good agreement with numerical results.
