Navy scientists develop underwater laser communication technology

by anoop

A better tool for underwater acoustics has been developed by the researchers at the Naval Research Laboratory. The new system will use laser light to create sound underwater from a distance. If this works properly then the floating buoys will be a thing of the past if planes will have to communicate with submarines. Well how is this done? Well, for efficiently converting light into sound, light has to be concentrated to ionize a small amount of water which will absorb the laser energy and superheat. This will result in a small explosion of steam which is capable of generation atleast 220 decibel pulse of sound. Wow!
