We have investigated the third order nonlinear optical properties of pyrrole Schiff bases synthesized by condensing pyrrole-2-carboxaldehyde with two different diamines. The nonlinear optical measurements were performed using the nano- second laser pulses at 532nm wavelengthby employing the Z-scan technique. The Z- scan spectra reveal a large negative non-linear refraction co-efficient .The nonlinear refractive index was found to be of the order of 10-14cm2/W and the magnitude of third order susceptibility was of the order of 10-13esu. These compounds exhibit good optical power limiting property under nano-second regime and TPA (Two Photon Absorption) is the dominating process leading to the non-linear behavior.

Physical Quantities

The investigation of the action of the spring dynamic absorber, as well as the calculation of the physical quantities of the constructed model and animation, was carried out using non-linear methods of the Runge-Kutta type. Using only three references to the right-hand side of the differential equation, a method of the third order of accuracy is constructed, as well as two-sided approximations of the second order of accuracy. An explicit estimate of the error at each point of integration is given.

CdP0.03Te0.97 thin films were deposited at room temperature using thermal evaporation and annealed at 100 and 200°C. The effect of annealing temperature Tann on both dispersion energy Ed and oscillating energy Eo were studied. The lattice dielectric constant εL and free carrier concentration/effective mass N/m* were calculated for these samples. The values of the first order of moment M-1, the third order of moment M-3, and static refractive index no were determined. Both of dielectric loss ε\ and dielectric tangent loss ε\\ for these films increased with photon energy (hν) and had the highest value higher than the energy gap Eg. All of the optical parameters such as real part of optical conductivity σ1, the imaginary part of optical conductivity σ2 and the relation between Volume Energy Loss/ Surface Energy Loss (VEL/SEL) were determined. The linear optical susceptibility χ(1) increased with Tann. The influence of annealing temperatures on all of the non-linear refractive index n2, the third-order non-linear optical susceptibility χ(3), and non-linear absorption coefficient βc were studied. Both of the electrical susceptibility χe and relative permittivity εr increased with Tann and had the highest value higher than Eg. The dependence of density valence band, conduction band, and position of Fermi level Ef were studied.
