laser communication
Coherent beam messaging
Laser communication is the transmission of information using focused beams of light rather than radio waves.
The technology enables high-bandwidth data transfer between satellites, spacecraft, or ground stations: NASA's laser communication system transmitted data from the Moon at record speeds.
Also called optical communication or lasercom.
