Researchers Test Underwater Acoustic Laser

A U.S. Naval Research Laboratory team recently tested an underwater acoustic laser capability that might one day provide a source of voice or data communications for submarines; navigational data for submarines or underwater robots; and sonar to locate mines or other objects in shallow water—all from an aircraft and without the need for hardware in the water.

Communicating with or from a submerged submarine remains a challenge in the 21st century and often requires the submarine to surface, exposing crewmembers to potential danger.

Using trailing wires or buoys for submarine communications limits maneuverability and hinders stealth.
