Fiber optic cables are used in effective cable communication to send data. The maximum theoretical transmission efficiency of light sent through them is 92 percent. These fibers have drawbacks, but airborne laser signal transmission is incomparable to it. Researchers have been attempting to do the same across the air, though, for the past ten years, …
Physicists have just set a new record confining a self-focused laser pulse to a cage of air, down the length of a 45 meter-long (148 foot-long) university corridor.
