Space laser communication system adapted for underwater use

A remotely operated vehicle and undersea terminal emits a coarse acquisition stabilized beam after locking onto ...

What has deep space exploration and underwater work have to do with one another? Quite a bit, actually. Adapting a laser system called Lunar Laser Communication Demonstration (LLCD) that was used in 2013 to transmit data between lunar orbit and the Earth across a distance of a quarter of a million miles at a rate of 622 megabits per second, MIT's Lincoln Laboratories is developing a way for underwater workers and machines to communicate more effectively with one another.
