Scientists Have Created 'Smoke Rings' Made of Intense Laser Light

Researchers have created a vortex of light using a complex arrangement of lenses, lasers, 

 Smokers can also form these ringed shapes with their mouths.

The feat was achieved by a team of researchers at the University of Shanghai for Science and Technology, China.

These self-focused and very intense laser beams can create a swirl of energy 

The research led by Howard Milchberg called these rings of light “Spatiotemporal optical vortices.”

The specially designed laser pulse was first sent into a long pipe-like vortex. 

This resulted in the light waves spinning and curling around the surface of the pipe, due to the light energy.
