We present the studies of the third- and higher-order nonlinear optical processes in barium titanate (BaTiO{sub 3}) and strontium titanate (SrTiO{sub 3}) nanoparticles. We measured the nonlinear refractive indices and nonlinear absorption coefficients of the BaTiO{sub 3} and SrTiO{sub 3} nanoparticles dissolved in ethylene glycol using the 790 nm fs and ps pulses. The high-order harmonic generation up to the 39th order was achieved in the BaTiO{sub 3} and SrTiO{sub 3} nanoparticles-contained plumes when the femtosecond radiation propagated through the preformed plasma. The 1x10{sup -6} and 4x10{sup -6} high-order harmonic efficiencies at the plateau region were achieved in the cases of the BaTiO{sub 3} and SrTiO{sub 3} nanoparticles-contained plasmas.
