Third-order non-linear optical effects

Fig. 36.25. Relative importance of electronic and vibrational contributions for various third-order non-linear optical effects.

The 38-metal-atom cluster (Ph3P)j2Auj8Ag2oCli4 is reported to be a highly efficient optical limiter in a polymer matrix or in solution. It was proposed that the optical limiting behavior is related to the third-order non-linear optical effect.
