利用高度非线性混合光纤和飞秒光纤激光器，实现了宽带1180 ~ 2100 nm的平加宽超连续谱（SC）产生。证明了无精细结构的稳定光滑光谱。混合纤维是由不同性能的纤维融合拼接而成的。在数值分析的基础上，通过对混合光纤的优化设计，可以合理地控制SC谱。产生的SC脉冲具有较低的相对强度噪声（RIN）。
We present wideband of 1180-2100 nm, flatly broadened supercontinuum (SC) generation using highly nonlinear hybrid fibers and femtosecond fiber laser. Stable and smooth spectra without fine structure are demonstrated. The hybrid fibers are constructed by fusion splicing fibers with different properties. The SC spectra can be properly controlled by the optimal design of the hybrid fiber based on the numerical analysis. The generated SC pulse shows the low relative intensity noise (RIN).
