Abstract:The role of the phase-dependent nonlinear processes that accompany the interaction of a weak signal wave with an intense pump wave is investigated for the case of the pump frequency being a multiple of the signal frequency. Phase relations that provide the maximum absorption of sound by sound are determined. It is shown that, as the frequency ratio of the waves increases, the role of the phase-dependent absorption rapidly decreases and becomes negligible.
