Abstract: The data of experimental investigation of optical properties of colloidal solution, its composition and morphology of the dispersed phase, resulting from laser ablation of zinc in aqueous solutions of surfactants — sodium dodecyl sulfate ($\mathrm{SDS}$) and dioctil sodium sulfosuccinate (AOT) are presented. It is shown that an optical absorption spectra of the colloids, $\mathrm{X}$-ray spectra and AFM (atomic force microscopy) images solid phase of colloids can trace the dynamics of synthesis $\mathrm{ZnO}$ nanostructures from zinc nanoclusters in the size of nanometers to fractal aggregates (FA) up to hundreds of nanometers. Determinants of this process are the average power and duration of irradiation, the frequency of the laser pulses, the colloid aging time, the type and concentration of surfactant in the solution. At the selecting of appropriate regimes of the process, along with zinc oxide other nanoproducts-hydrozincite and organic-inorganic layered composite $[(\beta)-\mathrm{Zn(OH)_2+SDS}]$ are obtained.
