The installation was described permitting to study accumulation and relaxation processes of space change and electric field connected with it. The spatial resolution of the installation when using OGM-20 laser was ≈100 μm for polymethylmethacrylate samples. The spatial resolution can be reached to several micrometers due to nanosecond LP-3 lasers, providing the formation in solid state media of acoustic signals of the length up to several nanoseconds and below. In connection with it the investigation of thin (tens-hundreds micrometers) dielectric and polymer films is possible.

Andriyanov Yu.V., Andriyanova O.N., Kozodoj P.V. «An electromagnetic acoustic shock wave generator» Приборы и техника эксперимента, 42, № 2, с. 254-260 (1999)

An electromagnetic acoustic shock wave generator with a parabolic reflector and a band foil inductor as a radiating element inside a metallic cylindrical shell is described. The electromechanical model calculated allows for evaluating the optimal number of turns (layers) of the band coil depending on the geometric parameters of the radiator. A model generator specimen ensured the stepwise variation of the acoustic pulse duration from 1 to 3 μs at a pressure amplitude of ≈100 MPa at the focus. The possibility of generating two successive acoustic pulses of different duration with a controlled time delay between them is considered. The device can be applied in medical facilities for destruction of kidney stones and gallstones, and the high stability of the parameters of acoustic pulses may be of interest in studying the biology of cell cultures (sonoporation), acoustic cavitation, etc.
