|Title:||High-order Optical Nonlinearities In Saturable Absorbers.|
|Abstract:||We present an experimental and theoretical study of self-diffraction in saturable absorbers, concentrating on the case of high-intensity beams interfering within the medium. We have observed fourth-order coherent scattering in DODCI. In our theory, which is not perturbative and is in quantitative agreement with the experiment, high-order scattering arises from the nonsinusoidal spatial modulation of the population grating.|
