“…The third order susceptibility of ZTS is 3.5 ± 0.17 x 10 -4 esu. The value of χ (3) is found to be larger than the other well known compounds [11] and it is due to the π-electron cloud movement from the donor to acceptor which makes the molecule highly polarized. …”

Optical absorption of tris thiourea zinc sulphate (ZTS) single crystals has been measured and its direct band gap was found to be 3.6 eV. Theoretical calculations were carried out to determine the linear optical constants such as extinction coefficient and refractive index. Further the optical nonlinearties of ZTS have been investigated by Z-scan technique with He-Ne laser at 632.8 nm. The nonlinear refractive index, absorption coefficient and third order susceptibility is found to be in the order of -5.36 ± 0.26 x 10 -12 cm 2 /W, 4.24 ± 0.21 x 10 -4 cm/W, 3.5 ± 0.17 x 10 -4 esu respectively. Thus optical characterization of ZTS reveals the various industrial application oriented properties of the material.

“…Interestingly, this value is more than two orders of magnitude larger than the value of nonlinear crystals such as LiNbO 3 [14]. For a strong nonlinear response, it is necessary to couple incident radiation efficiently into the nonlinear material, but, as metals are reflective, only a small portion of the incident fields contribute.…”

We investigate the nonlinear optical response of a noble metal surface. We derive the components of the third-order nonlinear susceptibility and determine an absolute value of c (3) ≈ 0.2 nm 2 V −2 , a value that is more than two orders of magnitude larger than the values found for typical nonlinear laser crystals. Using nonlinear four-wave mixing (4WM) with incident laser pulses of frequencies u 1 and u 2 , we generate fields oscillating at the nonlinear frequency u 4WM = 2u 1 − u 2 . We identify and discuss three distinct regimes: (i) a regime where the 4WM field is propagating, (ii) a regime where it is evanescent, and (iii) a regime where the nonlinear response couples to surface plasmon polaritons.
