中文摘要	We report the third-order optical nonlinearity of ferroelectric thin films of Mn doped Ba0.6Sr0.4TiO3 using Z-scan measurement with femtosecond laser pulses at 800 nm. The nonlinear refraction index and two-photon absorption coefficient are measured to be 3.0 x 10(-4) cm(2)/GW and 1.7 cm/GW, respectively, which are about one order of magnitude larger than those of the undoped Ba0.6Sr0.4TiO3 thin films. The enhancement is attributed to the acceptor behavior of Mn ions dopant. The figure of merit, T, defined by T=beta lambda/n(2), was calculated to be 0.44, less than 1. The results indicate that the thin films have great potential applications in nonlinear photonic devices. (C) 2011 American Institute of Physics. [doi:10.1063/1.3527969]
