摘要：

Laser ablations of silver and copper targets in water were performed to prepare nanosize metal colloids. The influence of the laser wavelength, focusing conditions, and laser fluence on the ablation efficiency was studied. The relation between the ablation efficiency and wavelength varied with laser fluence. The ablation efficiency at shorter wavelengths was higher at low fluence, while the ablation efficiency at longer wavelengths was higher at high fluence. These findings were discussed in terms of the "intra-pulse" and "inter-pulse" self-absorptions of the incident laser light by colloidal particles. (C) 2001 Elsevier Science B.V. All rights reserved.
