Airy Beams- Light Rays Moving Without Diffraction In A Curved Arc In Free Space

One of the earliest lessons science students learn is that a beam of light travels in a straight line and fan out, or diffract, as they travel. Recently it was discovered that light rays can travel without diffraction in a curved arc in free space. These r ...
