摘要

This work reports on the optical nonlinearities of a newly synthesized pyrazole derivative, namely (E)-1-(4-chlorophenyl)-4-(2-nitrovinyl)-1H-pyrazole. The Z-scan technique with femtosecond laser pulses was used to determine the two-photon absorption (2PA) cross- section spectrum, which presents a maximum of 67GM at 690nm. We have combined hyper- Rayleigh scattering (HRS) experiments and second-order Møller–Plesset perturbation ...
