I wonder if this technolgy will provide an alternative to communicating with satelites in space. I think using this underwater laser system is great because it provide security from signals being intercepted.
- streety 17y agoI don't believe this is relevant to ground-to-space communications. The way I read the article the laser pulse has a short range, ionising the water in the vicinity of the buoy, which creates sound waves which emanate out to wherever the sub is. The laser isn't bouncing back and forth from sub to buoy. As the communication is via sound and not laser it also means that anyone else in the vicinity could intercept the message. Strong encryption and authentication would still be required.
