Dynamics of Pearcey pulses in highly noninstantaneous Kerr media

摘要

We investigate the dynamics of Pearcey pulses in the highly noninstantaneous Kerr media. Setting appropriate pulse power and relaxation time of the media, an interesting phenomenon is found that the Pearcey pulse will exhibit an energy transfer property during propagation. We further investigate the evolution characteristics by changing the pulse power and relaxation time of the media, while keeping a constant ratio in the simulation. It is shown that the transversal motion of Pearcey pulses is proportional to the ratio between the pulse power and relaxation time of the media in the highly noninstantaneous limit.
