| 摘 要： | 采用理论数值分析的方法，研究了较大谱宽的飞秒激光脉冲在较大的非线性系数和非线性色散的有机高聚物中，由于非线性色散而导致其啁啾特性的变化，并进而从脉冲的啁啾特性上，解释了光谱的有效展宽，以及脉冲的自频移等脉冲在光谱上的变化．

| Abstract: | We study the chirp characteristics of femtosecond laser pulse propagating in conjugated polymer with larger nonlinear dispersion effect by means of theoretical and simulated methods. From the chirp characteristics of femtosecond laser pulse, the explanation for effective spectrum broadening and self-frequency-shift is given. |
