Characteristics of supercontinuum generation under the influence of a weak continuous-wave trigger

Abstract

In this paper, we numerically studied how a minute CW trigger could affect the properties of the picosecond SC generation in detail. In particular, we observe that the enhancement in the SC bandwidth in general can be achieved at the expense of temporal coherence, or vice versa. We also find that that depending on the wavelength of the CW-trigger the multiple higher-order, four-wave mixing (FWM) components generated by the CW-trigger can create either a relatively more stochastic or a more deterministic beating effect on the pump pulse, which has a significant effect on the onset of SC in the presence of noise.
