Как говорится в сообщении к видео, размещенном на канале Youtube, акустическая лазерная пушка была разработана учеными Министерства обороны США. С помощью лазерно-индуцированного плазменного эффекта эта пушка создает свет и звук. Пока это просто сильный и противный звук. Но ученые уверены, что смогут в течение трех лет найти возможность, чтобы пушка генерировала такие звуки, чтобы человеческое ухо воспринимало их, как понятные слова. 

Оружие состоит из двух частей: во-первых, фемтосекундный лазер, который создает вспышки сфокусированного света в течение 10-15 секунд. Этого достаточно, чтобы вырвать электроны из молекул воздуха и создать шар плазмы. В сообщении говорится, что плазму иногда называют четвертым состоянием вещества. Это поле электрифицированного газа, очень чувствительно к электромагнитным эффектам. По этому плазменному полю ударяет второй лазер — нанолазер, который настроен на чрезвычайно узкий диапазон длин волн. Таким образом генерируется не только свет, но и громкий звук.

Смысл в том, что шар плазмы можно получить на расстоянии в 30 км и заставить его «говорить». Никакие самые мощные динамики на такое расстояние работать не будут.
