Abstract
Colloid formation with laser ablation in solution was examined to investigate the influence of wavelength and focus conditions of irradiation. The wavelength dependence of the ablation efficiency was different between the focused and nonfocused conditions. Reabsorption of incident beam by colloid particles was suggested to be effective under the focused condition.
