Playing with light to produce sound seems routine for scientists now. They are doing it pretty effortlessly, but this latest achievement by Scientists at the Naval Research Laboratory wherein they have developed a laser light to remotely create sounds underwater, seems a turning stone for a whole new dimension in underwater acoustics.
Led by Dr. Ted Jones, the team of scientists has worked out a way to create sound by ionizing a limited volume of water with the lasers, which as effect superheats into steam generating about 220 decibel pulse of sound. Perfect application to revolutionize communication in both naval and commercial aquatic ventures, the new acoustic source with the driving laser pulse has ability to travel through both air and water.
