数值研究了飞秒超连续介质产生光异常波的特性，并利用连续波触发机制控制飞秒超连续介质的产生。详细的仿真结果首次表明，弱连续波触发器可以操纵飞秒SC波段的光异常波行为。所提出的连续波触发技术只需要波长调谐，并且是一种方便的主动控制连续波的方法，可以大大拓宽合成谱，并且在相干性和强度稳定性方面都可以显着改善连续波的噪声特性。
We numerically study the characteristics of optical rogue waves in the femtosecond supercontinuum (SC) generation and use the CW triggering mechanism to control the SC generation. Detailed simulation results show for the first time that a weak CW trigger can manipulate the behaviors of optical rogue waves in the femtosecond SC regime. For the proposed CW triggering technique which requires only wavelength tuning and is a handy approach for the active control of SC, the resultant spectrum can be greatly broadened, and the noise properties of the SC can be significantly improved in terms of both of the coherence and intensity stability.
