Abstract-In this experimental research work Al nanoparticles were prepared by pulse laser ablation (PLA) of a high purity aluminum bulk in distilled water. The beam of a Q-switched Nd:YAG laser of 1064nm wavelength with pulse width at 7ns and 10 Hz repetition rate. Aluminum bulk was placed on the bottom of water that height of water on the aluminum target was 1.2 cm. Aluminum target was ablated with 500 laser pulses at different fluencies. Samples 1-5 were prepared with laser pulse fluencies of, 1, 1.5, 2, 2.5, and 3 J/cm2 respectively. Formation of nanocrystals has been confirmed by electron microscopy imaging. Optical absorption spectra of colloidal nanoparticles have been and the production rate of nanoparticles in water is measured
