In ultrashortpulsed laser heating, two effects become important. One is the nonFourier effect in heat conduction. The other is the coupling between temperature and strain rate, which causes transform of mechanical energy associated with the stress wave to thermal energy of the material. In this work, a generalized solution for the coupled thermoelastic vibration of a microscale beam resonator induced by pulsed laser heating is developed. The solution takes into account the above two effects. The finite sine Fourier transformation combined with Laplace transformation is used to obtain the lateral vibration of the beam. And the paper analyzes the effect of different laser pulse energy absorptive depth and environment temperature.
