Abstract	Transparent oxide semiconductor (TOS) thin films made of ZnO nanocomposites, which are used as transparent electrodes in optoelectronic devices, have been widely reported. Among the TOSs, the thin films of a homologous compound, with a so-called superlattice structure have attracted considerable interest. Because of the spatial confinement of conductive electrons in the two dimensional layer, their interesting electronic, optical, and magnetic properties, along with small size and chemical reactivity, have led to a wide range of applications in nano-optoelectronics, medical diagnostics, catalysis, and chemical sensing. In this paper, the nonlinear optical properties of metal nanocomposites were investigated. Heat treatment has been proven to be a feasible way to improve the performance of ultrafast response for this kind of materials. Based on the experimental results of Al-doped ZnO materials excited by intense fs pulses near 800 nm, nonlinear optical effects that may emerge under an intense field are attributed to be responsible for the efficient two-photon absorption process under detuned excitation.
