What is it about?
Femtosecond third order nonlinear optical (NLO) properties of ultrafast laser ablated gold (Au) colloids in distilled water are investigated using degenerate four wave mixing technique with 50fs pulses at 800 nm wavelength. The estimated value of χ(3)obtained for Au nanoparticles is 1.93×10^-14 e.s.u. The characterization of the NPs was achieved done using TEM and HR-TEM techniques. We also present the time resolved studies of Au colloids by using DFWM technique in the forward BOXCAR phase matching geometry.
