Abstract
The effects of elastic nonlinearity in KRS-5 and NaBi(MoO4 )2 are under discussion. Under rather low power of input signal (<1 W), high acoustic harmonics with frequencies up to 2.5 GHz in KRS-5 crystal and up to 5 GHz in NaBi(MoO4)2 were detected. The theoretical and experimental spatial dependences for acoustic harmonics under different power levels of input signal are presented. The influence of signal level on the attenuation coefficient for acoustic waves is shown. Based on the experimental data, a waveform of deformed wave is synthesized. Some data on the measurement conditions and the parameters of elastic nonlinearity in several known acousto-optic materials are presented
