✦ Synopsis

We performed the femtosecond two-color collinear optical Kerr shutter (OKS) measurements in a thick Kerr medium. The time-resolved OKS signals showed a multi-peak structure and a large broadening with respect to that for non-collinear. By measuring the time-resolved OKS signals in the sample at different powers, we demonstrated that the abnormal profile of the OKS signals was mainly attributed to self-focusing and refocusing of the pump beam in the Kerr medium and the group velocity difference between the pump and the probe beams.

In this work we numerically compare the interaction of optical vortices (OVs) in self-defocusing and selffocusing Kerr nonlinear media. We find that the basic scenarios (attraction/repulsion, translation/rotation vs. background) in the interaction of two and three vortices with equal and alternative

In this paper, it is numerically simulated that two optical beams with oneΓ•s intensity much stronger than the other propagate simultaneously in opposite directions in a two-dimensional self-defocusing nonlinear medium. The results show that the weaker probe beam can be induced to focus due to cross-
