摘要
本文深入讨论了脉冲啁啾的非线性起源及其对干涉相关测宽(等值宽度和条纹计数)法的影响。提出根据干涉相关曲线下包络最大值位置适当降低等值宽度位置和用计算机平均处理干涉相关信息的技术以消除啁啾的影响。
The nonlinear origin of pulse chirp and its effect on interference-correlative measurement of fs pulse width(i.e.equivalent width and streak coun-ting) are deeply discussed. In order to eliminate the effect, it is presented prop-erly to lower the position of equivalent width according to the lower-envelopemaxmun position of interference-correlative cruve and to average the cruve withcomputer.
