Effects of two weak femtosecond pulse seeds on promoting rogue wave generation

Abstract

We numerically simulate the enhancement of rogue wave generation by adding two weak femtosecond pulse seeds at two fixed modulation frequencies. The results show that two weak pulse seeds have better promotion effect on rogue wave generation than one weak pulse seed. In addition, the modulation depth and pulse width of the weak pulse seeds also affect the generation of rogue wave. With the increase of the modulation depth and pulse width of the two weak pulse seeds, the control effect of rogue wave gradually becomes better.
