“…On the other hand, we present evidence that signatures of a higher-order nonlinearity can be found in the low-order harmonics of the pump center frequency. Second, 3D atomic quantum simulations, e.g., [12,13], involve separating the nonlinear response from the much larger linear response in the full optical response, and this can be prone to numerical issues. It was recently shown in [14] that the 1D atomic model allows for an exact solution for the nonlinear optical response, making it immune to numerical issues, so that qualitative comparison between the more precise 3D atomic model and the reduced 1D atomic model can serve to bolster the conclusions of [11,12].…”

On the relative roles of higher-order nonlinearity and ionization in ultrafast light-matter interactions

Far off-resonant ultrafast and nonlinear light-matter interactions are studied using a one-dimensional atomic model. Results from a pump-probe diagnostic reveal that any higher-order nonlinear refraction is masked by ionization-induced defocusing before it becomes significant. On the other hand, we show that signatures of a higher-order nonlinearity may still be manifest via low-order harmonics of the pump center frequency. Implications for filamentation of femtosecond pulses are pointed out.

We present results of ah initio numerical calculations for low-order-harmonic generation as well as calculations of the higher-order terms in the respective perturbative power-series expansions of the susceptibilities for thirdand fifth-order-harmonic generation. We find that the transition from perturbative to nonperturbative interaction in these low-order nonlinear processes occurs at about 10B W /cm2. Our findings confirm previous results that any deviation from the predictions of lowest-order perturbation theory indicates that the perturbative series expansion is not applicable and, if required, needs to be replaced by a nonperturbative treatment of the interaction between the atom and the field. In particular, the results also show that the observation of low-order-harmonic yields cannot be considered as a test of higher-order Kerr effects.
