| Abstract: | A modulated continuous wave argon ion laser has been used to get lamb waves in silicon membrane. In this report, the basic principles of conversion for optics to thermal then acoustic waves are deduced. The experimental set - up, the analysis of the results and the possibl way to obtain a given mode of lamb wave are described. |
