Laser ablation of a solid target in a confining liquid provides a highly effective means to synthesize the nanoparticles. It has demonstrated the following advantages: (i) a chemically “simple and clean” synthesis, (ii) an ambient conditions not extreme temperature and pressure, and (iii) the new phase formation of nanoparticles may involve in both liquid and solid. These advantages allow us to combine selected solid targets and liquid to fabricate compound nanostructures with desired functions. The size of nanoparticles is greatly crucial, which relate directly to the properties. To fabricate smaller nanoparticles which possess better biological, optical and catalytic performance, the ultrasonic is critical in the process. Here we combine the laser ablation in liquid with the ultrasonic to produce the metal nanoparticles and compare them with the situation which only uses the laser ablation.
