Abstract
An analytical model of cylindrical surface waves excited thermoelastically by a pulsed-laser line source is presented. The laser-generated transient response of the cylindrical Rayleigh wave and the first three whispering gallery (WG) modes of an aluminum cylinder are calculated from the model using residue theory and the fast Fourier transform technique. The superposed wave form of the four transient modes is in excellent agreement with the wave form obtained from experiment and reveals that the peaks observed in experimental data are the result of wave-form interference from the superposition of all WG modes.
