The systematic method of Fokker-Planck equation (FPE) of the generalized Wigner distribution is used to study the multi-photon transition process of a driven optical system, which has the mixture of absorptive and dispersive feature. The multi-photon and mixture of absorptive and dispersive feature FPE and steady state equations are obtained. The properties of the steady state equation is discussed.

Phase transformation and electrical properties of lanthanum modified lead zircono stanno titanate (Pb 1 x La 2 x /3 )(Zr 0 6 Sn 0 3 Ti 0 1 )O 3(0 00≤ x ≤0 12, PLZSnT)ceramics with a composition near antiferroelectric/ferroelectric(AFE/FE) phase boundary were investigated by dielectric spectroscopy, Sawyer Tower polarization technique, and X ray diffraction. It was found that, as lanthanum content increases, the ferroelectric rhombohedral phase( x =0 00, FE R) transforms to antiferroelectric tetragonal (0 03≤ x ≤0 09), and cubic phase( x =0 12, PE). In the phase diagram of the PLZSnT system with x =0 06, AFE t region has been extended to 18 at%Ti. A diffused AFE→PE phase transition with dielectric frequency dispersion, is observed in PLZSnT specimens with high Zr and high Sn contents, which is proved to be an antiferroelectric relaxor. A kind of \!slant, narrow\" double hysterisis loops, and a peculiar \!triple hysteresis loops\" were observed in the specimens with a composition near AFE/FE phases boundary due to the coexistence of FE and AFE phases. Effects of lanthanum modification on the phase transformation and electrical properties of Pb(Zr,Sn,Ti)O 3 AFE ceramics were discussed based upon the tolerance factor and lattice structure of AFE phase.
