【摘要】 Airy脉冲和Pearcey脉冲等非对称型脉冲具有独特的震荡拖尾结构和复杂的传输特性，因此，本文对非对称脉冲泵浦产生超连续谱的特性进行研究。通过数值模拟研究非对称型脉冲的脉冲参数对超连续谱产生的影响；通过控制变量法，逐步分析由初始脉冲峰值功率和初始啁啾引起的脉冲传播行为变化。结果表明：在相同参数下，Pearcey-Gaussian脉冲展宽效果更好；同时，在反常色散区，正啁啾会有利于超连续谱的产生。此外，进一步考虑了非对称型脉冲特有的两种脉冲参数对超连续谱的影响，发现截断系数小、分布因子小的脉冲产生的超连续谱特性更优。更多还原

【Abstract】 The asymmetric pulses such as Airy pulse and Pearcey pulse have unique oscillating trailing structure and complex transmission characteristics. Therefore, the characteristics of supercontinuum generation by asymmetric pulse pumping are studied in this paper. The effect of the pulse parameters of asymmetric pulse on the supercontinuum spectrum is studied through numerical simulation. The change of pulse propagation behavior caused by initial pulse peak power and initial chirp is analyzed step by step by control variable method. The results show that the Pearcey-Gaussian pulse broadening effect is better under the same parameters. Meanwhile, in the anomalous dispersion region, the positive chirp is beneficial to the generation of supercontinuum. In addition, the influence of two pulse parameters on the supercontinuum spectrum is further considered, and it is found that the pulse with small truncation coefficient and small distribution factor produces better supercontinuum characteristics.更多还原
