The thirdarder microscopic hyperpolarizability y is calculated for finite bridged polymers of the form A-B-A-B-... using simple model Hamiltonians. Generally, the even-and odd-numbered chains show markedly different behavior, with the addition or subtraction of one chain unit resulting in a predicte
Au films of thickness ranging between 5 and 52 nm were prepared by sputtering on quartz substrates and their third-order nonlinear optical response was investigated by Optical Kerr effect (OKE) and Z-scan techniques using 532 nm, 35 ps laser pulses. All prepared films were characterized by XRD, AFM
