It is suggested that nonlinear acoustic waves excited by distributed sources be analyzed by a nonhomogeneous equation of simple waves. An analytic description is obtained of the generation of intensive sound in a periodically strictive field, produced by two head-on laser beams. A set of coupled quasilinear equations describing the behavior of the incident and reflected waves in a slightly nonhomogeneous medium is obtained. It is shown that the mathematical tools developed in the present paper are suitable in the case of periodic nonhomogeneities.
