FIG. 1.

(a) Sample structure. The adjacent materials (PDMS, parylene, or polyimide) coated a thin metal film (Cr, Ti), deposited on a fused quartz substrate. (b) Schematic diagram of the experimental setup. A Nd:YAG laser was applied uniformly to the sample using a homogenizer, and the laser-induced acoustic wave was measured by a hydrophone.

FIG. 2.

Transient voltage signal of the laser-induced acoustic wave, as measured by the hydrophone. The adjacent materials used were: (a) PDMS on Cr, (b) parylene on Cr, (c) polyimide on Cr, and (d) parylene on Ti.
