|Abstract:||Ferroelectric Bi0.9 La0.1 Fe0.98 Mg 0.02 O3 thin films with high optical quantity were deposited on quartz substrates by radio frequency magnetron sputtering at 650°C. The interplay between third- and fifth-order optical nonlinearities is observed by performing Z -scans under femtosecond laser excitation with 1.60 eV photon energy. The measured third-order nonlinearities mainly originate from electronic Kerr effect and two-photon absorption (2PA), while the population redistribution assisted by 2PA leading to an equivalent stepwise X3: X1 process is the main mechanism of the fifth-order effect. © 2009 American Institute of Physics.|
