摘要
The nonlinear properties of Bi3.25La0.75Ti3O12 thin film grown on quartz substrate is measured using the Z-scan technique with ps-laser pulses at 532-nm wavelength. The nonlinear refractive index and absorption coefficients are 0.31x10(-9) cm(2)/W and 3x10(-5) cm/W, respectively, indicating Bi3.25La0.75Ti3O12 film on quartz is a good candidate for applications in nonlinear optical devices.
