Abstract : The cross sections for second harmonic generation of surface acoustic waves have been calculated from the rigorous theory of thermoelasticity. In this treatment, the nonlinear wave equation is satisfied by mechanical displacements which also maintain the boundary stress free at the harmonic frequency. Calculations for various cuts on alpha-quartz and sapphire are presented. (Author)
