This actually happened in the state of Maryland, and given all the other sciency stuff in the state (the James Webb Space Telescope, the asteroid redirection mission, the NIH and NSA and NASA and universities like Johns Hopkins and UMBC and University of Maryland - College Park (and a few others), it's apparent they we are high on the nerdy pyramid.
So it should not be a surprise that what is described in this article happened here, too.
Nearly 50-meter Laser Experiment Sets Record In Campus Hallway
"Their efforts were to temporarily transfigure thin air into a fiber optic cable—or, more specifically, an air waveguide—that would guide light for tens of meters. Like one of the fiber optic internet cables that provide efficient highways for streams of optical data, an air waveguide prescribes a path for light. These air waveguides have many potential applications related to collecting or transmitting light, such as detecting light emitted by atmospheric pollution, long-range laser communication or even laser weaponry. With an air waveguide, there is no need to unspool solid cable and be concerned with the constraints of gravity; instead, the cable rapidly forms unsupported in the air. In a paper accepted for publication in the journal Physical Review XPhysical Review X the team described how they set a record by guiding light in 45-meter-long air waveguides and explained the physics behind their method."
