In this research, (Pd-Ag core-shell nanoparticles) was prepared using (PLA) technique with (Nd-YAG) laser at a wavelength of 532nm, a power of (1J) and a number of different laser pulses. The structural properties (Pd-Ag core-shell Nps) were studied. The average physical size of the nanoparticles was obtained through (XRD and SEM) examination, and it increased with the increase in the number of laser pulses. The EDX examination showed that the prepared samples were of high purity. The results of optical properties tests showed an increase in absorbance and absorption coefficient and a decrease in transmittance with increasing number of laser pulses.
