“…2,3 Unfortunately this error seems to be quite indicative of the later development with numerous measurements using different techniques obtaining data for the hyperpolarizability of C 60 scattered between 10 Ϫ24 and 10 Ϫ35 esu, i.e., an indeterminacy of 11 orders of magnitude. [4][5][6][7][8][9][10][11][12][13][14][15] Such discrepancies reflect many different problems encountered in experimental measurements as discussed in Ref. 15 and as also commented below.…”

The linear polarizability, α, and the second hyperpolarizability, γ, of C60 in gas phase have been computed by ab initio cubic response theory in the random phase approximation and with an efficient parallel implementation. With a tailored, well-tested, basis set, containing more than 1000 contracted basis functions the average values of α and γ are predicted to be 8.58×10−23 cm3 and 5.73×10−35 esu, respectively, which are about 8 and 9 times larger than the corresponding values for benzene calculated at the same level of accuracy.

Using picosecond laser operated at 532nm, the observed time-resolved degenerate-four-wave-mixing(DFWM) spectra of nonether polyphenyiquinoxaline (PPQ) solution show significant change in optical nonlinearity with changing solvents. For PPQ in cresol the DFWM spectrum obtained is composed of an instantaneous coherent optical response signal associated with the third-order susceptibility and a rapidly damped, laser-induced acoustic phonon signal. The lifetime of the generated acoustic phonon was estimated to be 1 .5 ns. For PPQ in chloroform, an anomalously enhanced phonon signal overwhelms the intense coherent component. The generated acoustic phonon in PPQ-chloroform is much longer-lived. The mechanism of the observed optical response is discussed and the value is calculated through resolving the coherent peak from the intense phonon signal.

“…Degenerate four-wave mixing (DFWM ) is a useful technique for studying the third-order nonlinearities in these molecules [8,9]. DFWM in the nanosecond time domain on C 60 and C 70 -toluene solutions using nanosecond laser pulses at 365 nm has been performed, and it is suggested that a thermal mechanism is responsible for the long-lived component of the third-order nonlinearity [10].…”

We report laser-induced spatial self-phase modulation in C 60 -toluene solution using a low-power continuous-wave He-Ne laser. An experiment is performed to measure the thermal diffusivity of a nonlinear medium using thermal self-defocusing phenomenon. We have measured several parameters in this study, for example the local change in refractive index Án(r), the ratio (@n/@T )/k of the temperature coefficient of the refractive index to the thermal conductivity, the time constant c and the thermal diffusivity D of the thermal blooming. The self-focusing effect of the liquid medium is also observed.
