چکیده انگلیسی
Ten new organic donor-Ï-acceptor compounds were synthesized and characterized by UV, IR, 1H NMR and elemental analysis. Off-resonant third-order nonlinear optical properties of the compounds were measured using femtosecond laser and degenerate four-wave mixing technique. The third-order nonlinear optical susceptibilities Ï(3) were 3.50-4.29 Ã 10â13 esu. The nonlinear refractive indexes n2 were 6.42-7.89 Ã 10â12 esu. The second-order hyperpolarizabilities γ of the molecules were 3.63-4.47 Ã 10â31 esu. The response times were 69-112 fs. The results show that these compounds have potential nonlinear optical applications.
