Paper Abstract

Experimental results of the study of nonlinear propagation of phase conjugated ultrasonic beam in water are presented. Time waveforms were measured using spectral analysis of light diffraction by the sound field, which permits digital acquisition of signal pulses. Data processing and analysis were carried out in approximation of Raman-Nath conditions. For high intensity ultrasound the method based on direct connection between amplitude of Raman-Nath spectra and Fourier components of ultrasonic wave was developed.
