Abstract

The process of liquid ablation by pulsed laser (PLAL) was applied to prepare Cu@Ag core-shell nanoparticles in PVA solution in two steps. To find the preparation and investigation of the morphological and nonlinear optical (NLO) properties were used an Nd: YAG Q-switched: (6 Hz, 1064 nm, 160 mJ, and the number of pulses is 500) for Cu NPs in PVA solution and put the silver piece in Cu nanopolymer using
