摘要：

We demonstrate the existence of chi(5) nonlinearities induced in a transparent glass by intense femtosecond pulses at 620 nm. Polarization selectivity associated with a transient-grating technique allows us to discriminate this contribution from the electronic third-order one. A value of 5 is measured for the ratio between symmetric and nonsymmetric elements for this fifth-order susceptibility. This value corresponds to the expected value deduced from the anharmonic model presented and is definitely attributed to a direct six-wave mixing process.
