Researchers at The Pentagon just finished a new round of testing on a weapon that makes lasers talk.
As a part of a military initiative called the Joint Non-Lethal Weapons Directorate (JNLWP), the project aims to create laser weapons that can transmit clear snippets of human speech across long distances. To accomplish this task, the weapon uses a principle called the Laser Induced Plasma Effect, which involves firing an incredibly powerful laser to create a ball of plasma, then shooting a second laser to oscillate the plasma, creating sound waves. With enough laser bursts fired at the right frequencies, the plasma vibrations can actually mimic human speech.
