Abstract
The distinction of the pure electronic instantaneous and the non-instantaneous (NI) nonlinear optical refractive index of materials, is not easy to do without using time-resolved methods. Usually, time-resolved method such as Kerr effect relies on two-beam use, which experimentally, can be complicate [1]. Here we propose a new single-beam, single-scan and self-referenced method based on the nonlinear ellipse rotation (NER) [2] to observe the NI nonlinearities contributions. We did measurements in silica (reference), CS2, and acetone with different pulse durations. As we going to see, the NI nonlinearities can be detected by following the changing of the NER signal with pulse duration.
