Embodiment Construction
[0022] The present invention is illustrated below in conjunction with the accompanying drawings, but the present invention is not limited.
[0023] Such as figure 1 As shown, first, the nozzle 4 ejects compressed air to form a certain pressure in the isolation chamber to protect the focusing lens 3; the working medium nozzle 8 ejects the working medium 7; the laser 1 emits a high-energy ultrashort pulse laser beam 2, which passes through the After focusing, the focusing mirror 3 passes through the tapered hole of the isolation plate 6, and then acts on the working medium 7 ejected from the nozzle 8, so that the working medium breaks down and generates a plasma explosion in the horn-shaped tube 9, and several GPa are generated inside the plasma The pressure, the formed plasma explosion shock wave excites the gas in the horn tube, when the pulse frequency of the laser 1 changes from 1 to 20HZ, infrasonic waves of different frequencies are formed.
