An international team of researchers has proposed and demonstrated an efficient approach for triggering, trapping and guiding electrical discharges in air. Their technology is based on the use of a low-power laser beam that traps and transports light-absorbing particles in mid-air. Experimental configuration and principles of optical vortex beam for …
