Abstract

An amplitude modulated continuous wave laser source is used to generate Lamb waves in thin plates. The source is a 1550nm electro-absorption modulated laser. The acoustic waves are detected with a Michelson interferometer operating at 532nm. This system provides narrow-bandwidth detection at frequencies up to 200 MHz with extremely high sensitivity. The dispersion curves of up to five Lamb modes were constructed for 50μm tungsten plate, and we demonstrate that the laser source couples very efficiently into the quasi-resonance at the S1 minimum frequency.
