| 摘 要： | 利用搭建的大臂长差相关仪，进行了飞秒激光脉冲序列间脉冲的互相关实验。实验结果表明：飞秒脉冲间互相关具有飞秒脉冲自相关的干涉相关图样。初步互相关实验和数据处理表明:利用飞秒脉冲固有的间隔和超短的脉冲宽度在μm量级上能精确标定大型光学谐振腔的长度；大臂长差飞秒脉冲相关技术，在未来加速器新光源装置中，可以用于稳定定时信号传输时间，更直接用于大型光学谐振腔的长度确定。

| Abstract: | Theoretical analyses have been done on the cross correlation between pulses of the femtosecond laser sequence. Experimental results are also derived using a cross-correlation setup, which can be switched between intensity cross-correlation mode and interferometric cross-correlation mode. The results show that the pattern of adjacent pulses cross-correlation is similar to that of auto-correlation. In the future, the method can be used in advanced light sources based electron accelerators to stabilize signals and to locate the cavity mirror precisely. |
