| Summary: | This research included study the effect of the pulse laser beam that type (Nd: YAG) on material piezoelectric, was chosen as the piezopolymer material polyvinylidene fluoride (PVDF) with thickness (9 m), in this test so as to possess unique properties vary rather more from other piezoelectric materials in terms of high flexibility, small size and ability to respond to high frequencies. The laser pulse was supply with high energies of (530 mJ to 570mJ) on PVDF polymeric material. The results that get it show, the shape of signal in multimeter equipment depend on the energy of laser beam. That is because of conversion of light waves (pulse laser) to sound waves. This process is called the phenomenon of the (photoacustic). Where we known the form of the resulting electrical signal for each amount of energy were used. |
