摘　　要：分析了载波相位引起的高斯形几周期无啁啾脉冲 (FCP)时间特性的变化 ,导出了高斯光脉冲携带的能量W ,脉冲时间重心〈t〉以及脉冲有效宽度τeff等与载波相位的关系式。分析结果表明 ,当包络脉宽 (FWHM)τP 小于载波周期时 。Carrier phase dependent characteristics of a few cycle chirp free Guassian pulse have been studied in the time domain. Expressions of the pulse energy W, center of gravity of the time 〈t〉, and effective pulse width τ eff  have been deduced in terms of the carrier phase . Results suggest that the carrier phase takes effect when the time width (FWHM) τ P of the pulse envelope becomes smaller than the period of the carrier oscillation period.
