Vortex rings, similar to smoke rings, have been observed in pulsing light before. Now, scientists have figured out how to make them on purpose with lasers, mirrors and special lenses
. They directed it through a sequence of gratings, mirrors, lenses and instruments similar to small liquid crystal screens, all of which changed the properties of the light.
This group of devices first transformed the laser pulse into a long, pipe-like vortex in which light waves spun as if they were curling around the surface of a cylinder. After travelling through another group of devices, this cylindrical vortex emerged with connected ends, forming a ring. Zhan compares the process to stretching out and then bending a “hurricane made of light waves” instead of air currents.at Xiamen University in China says that it is experimentally challenging to not only generate a vortex, but also reshape it from a tube into a ring. The protocol for doing so in this new experiment can probably be extended to generating other vortex shapes, he says. Zhan says that, for instance, it may be possible to engineer a knot rather than just a smooth ring.
