| 摘 要： | 用变分法讨论了飞秒脉冲在块状透明介质中超连续谱的产生，结合频谱展宽与非线性相移的关系，讨论了块状介质的长度、抽运光的功率、光束口径、透镜的焦距以及介质与透镜的相对位置对超连续谱光谱宽度和光谱稳定性的影响，结果表明入射功率为几倍自聚焦阈值功率时，超连续谱光谱稳定性最好。为实验上获得稳定的超连续谱光谱输出提供了理论指导。 |

| Abstract: | The filamentation and supercontinuum generation with femtosecond laser pulse in bulk material were discussed by using variational method. The influences of the supercontinuum bandwidth and spectral stability caused by the length and the relative positions of the medium and lens were discussed. When the input power is several times to that of selffocus threshold, the spectral stability is the best. The result provides the theoretic guidance for obtaining the stabile supercontinuum spectral. |
| Keywords: | supercontinuum spectral self-phase modulation nonlinear optics |
