#video | the Pentagon has demonstrated a laser acoustic cannon to disperse the rallies

Engineers from the Laboratory of non-lethal weapons of the Pentagon has shown an innovative acoustic laser guns, whose main task is to transfer deafeningly loud sound over long distances, up to tens of kilometers. In the future, the researchers plan to transmit with this device a synthesized human voice. Meanwhile, during the demonstration we show the basic working principle of the gun, which is based on laser radiation.

Cannon uses two types of lasers. Femtosecond laser creates the aimpoint plasma ball, which, in turn, the beam has a narrow range nanolaser. Plasma sphere responds to the impact of the deafening sound and bright flashes of light. During several field tests, the researchers were able to generate a plasma clot at a distance of thirty kilometers from the installation.

In addition to the stunning noise, the installation will soon learn how to transmit the human voice with the volume up to 150 decibels. Such non-lethal weapons the us military is planning to use in the course of military operations, and to disperse unauthorized rallies and protests. We offer you to see the video showing the installation in action. Be warned that the video is accompanied by a loud sound, so make in advance the volume of your speakers or headphones down a little bit.
