Heh. There's actually been a lot of research into blue-green lasers for undersea communication as they are precisely the right frequency to penetrate as far as possible through sea water and can carry much higher bandwidth signals.

Obviously the beam degrades much more quickly in water than air but it's possible to overpower that with newer, stronger lasers somewhat and it's still better than the alternatives, at least for data.
