    Laser ultrasonic technique has the potential as an access for quantifying skin property for diagnosis and accurate assessment for skin diseases. This paper presents a finite element (FE) modelling technique which studies the effect laser wavelength has on the generated surface acoustic waveforms in a multilayered skin model. By comparison, this paper discusses the suitability of using laser generated surface waveforms for the accurate non-destructive evaluation of skin layer mechanical and geometrical properties using surface wave phase velocity analysis.
