Laser-induced transient photoacoustic and photothermal waves in thin films of material
Photoacoustic wave with frequency of GHz and corresponding detection were researched. The PA in materials was excited by a mode-locked laser. The thickness of thin material was measured no- destructively by echo analysis. Also the laser induced photothermal wave studied. The measurement of sink energy can be used to illustrate damage mechanism of material.
