Infrasonic wave generator based on laser-induced shock waves
The invention relates to an infrasonic wave generator base on laser-induced shock waves, which comprises a high-energy ultrashort pulse laser, a focusing system, a working medium-jetting system and a flaring tube. The high-energy ultrashort pulse laser interacts with the substance jetted by the working medium-jetting system, so that a working medium can be broken down to form plasma, the ...

Vladimir Gavreau
His interest in infrasonic waves first came about in his lab during the 1960s, when he and his lab assistants experienced pain in the ear drums and shaking One of Gavreau's experiments involved an infrasonic whistle that, some say, has led to a line of research that has military applications.
