Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>Metal nanoclusters were produced by ion implantation (Cu⁺) in silica glass with dose of 2×10¹⁷ ions/cm². Third order non-linear optical properties of the nanoclusters were measured at 1064 and 532 nm excitations using the Z scan technique. The non-linear refraction index, non-linear absorption coefficient and the real and imaginary parts of the third order non-linear susceptibility were deduced. Results of the investigation of non-linear optical properties by the Z scan configuration are presented, and the mechanisms responsible for the non-linear response are discussed. Third order non-linear susceptibility <italic>χ</italic>³ of this kind of sample was determined to be 3·2×10⁻⁷ esu at 532 nm and 1·7×10⁻⁷ esu at 1064 nm respectively.</p> </abstract>
